The construction activity for urban development has seen a shift from over head and sur-face based utility lines to underground utility lines. These underground lines contributedby: telephone, power, cable TV, fibre optics, traffic signals, gas line etc are forming a kindof spider's web. This web gets further complicated in the scenario where deregulation ofthe services is leading to multiple players providing a given service. These utility lines areoften at risk of being damaged unknowingly during the process of excavation or con-struction either at the same place or in the nearby area. This lead to the urban develop-ment work, calling for coordination meet amongst the various service provider prior toany work being undertaken. This was quite evident when the reworking of urban infra-structure like city highways, telephone cable, power line was initiated.

All this only vindicates the move by the urban bodies to come up with urban SDIs. Thecity of Riyadh which has already taken a step in this direction in September 2006, will'enable public and private agencies to share mapping data and to distribute data changesand updates in near real-time.' The recent news of EU Satellite Centre [EUSC] with JointResearch Centre [JRC] providing scientific support to the international donors planningthe distribution of aid in Lebanon through provision of high resolution satellite imageriesis a step in this direction. It is said that the JRC and EUSC would establish an SDI fordetailed assessment of the damages and reconstruction planning. The Web GIS article'Digging Information System' for the city of Madinah is an initiative on similar lines withfocus on the coordination aspect for on-site construction. The availability of this systemon web increases the usability of this system. The Dubai GIS Center under the DubaiMunicipality [DM] is the one point source for spatial datasets like: base maps, landusemaps, infrastructure data and operations data. What is impressive the list of governmentand private partners which are listed as strategic partner to the DM, which would ulti-mately contribute to the updation of the spatial data sets maintained by DM. In Feb2006, a workshop was organized on SDI for UAE, the initiative which soon after wasapproved by the Emirates. The Qatar SDI has an excellent system data sharing amongstthe participating agencies, where the agencies can publish their data for sharing. Thedata sharing is regulated to be in the framework of national spatial data standards. Theseactivities are monitored by Center for GIS at Qatar.

The common denominator for all the virtues of urban SDI and the various initiatives tak-en would be the service to the stakeholders and the coordination amongst them. Theservice elements could be influenced by the amount of data which can be accessedthrough Web GIS Application. The enterprise solutions offered by leading geospatial ven-dors would continue to evolve, with a skeptical look by the general public: 'Will GoogleEarth or Microsoft Local Live, in future, to provide geospatial tools for utility service man-agement, a small domain compared to the issues they would like to address?'

BAHRAIN

Postal Dept. goeshi-tech Bahrain joined the interna-tional community in observ-ing the World Post Day(WPD) on October 9th, by fur-ther expanding its postalservices. Which includedlaunch of a new GPS naviga-tion system to monitor itsfleet of 80 vans in streamlin-ing mail delivery.

Under the new hi-tech sys-tem, the postal authoritieswill be able to track downeach van and check theassigned route, timings,speed and distance covered,said Shaikh Bader.

The new GPS system auto-matically warns the driver incase of traffic violations,locates his position andchecks whether he sticks tothe distribution zoneassigned to him.

The Bahrain Post is com-mitted to enhancing its serv-ices to international stan-dards, said TransportationMinistry Assistant Under-Secretary for Posts ShaikhBader bin Khalifa Al Khalifa.The number of post offices inBahrain were also increasedto 14 with the opening of apost office in Juffair lastmonth, he told the GDN.

"We are now upgradingthe services to make remit-tance instantly through elec-tronic channels," said ShaikhBader and added that peoplewould also receive non-pay-ment notices through thepost offices.

GIS to be adoptedto manage powersupplyBahrain is taking steps tohandle an anticipated 65 percent surge in electricity con-sumption over the next sixyears.

Major developments suchas Bahrain Financial Harbourand Durrat Al Bahrain areexpected to drive the mas-sive increase in demand.Consumption peaked at

1,840mw this year, said Elec-tricity and Water MinistryUnder-Secretary Dr MajeedAl Awadi during a meeting ofthe Bahrain French BusinessClub (BFBC).

Dr Al Awadi said severalmajor plans are underway tohelp the country cope withthe expected increase indemand, including the cre-ation of 15 new substationsand upgrading 10 existingones.

Moreover, he also men-tioned about several majorstrategies which are under-way to help the country copewith the expected increaseddemand .He said, an upgradeof the customer service sys-tem, set to be finished nextyear, and the introduction ofa GIS by November 2008would improve the handlingof reported faults.

Dr Al Awadi admittedupgrading work needed to bedone, but said the ministrywas battling against low rev-enue margins, old parts ofthe network, rapid changesin consumption patterns andunauthorised additionalloads.

He said an upgrade of thecustomer service system, setto be finished next year, andintroduction of a GIS byNovember 2008 wouldimprove the handling ofreported faults." The cus-tomer service system will beupgraded by the first quarterof 2007 and these two willhelp us a lot and make it eas-ier to correct problems".

LEBANON

EU helps inreconstructionThe European Commission'sJoint Research Centre (JRC),together with the EU SatelliteCentre (EUSC), is providingscientific support to interna-tional donors planning the distribution of aid inLebanon.

High resolution satelliteimages have helped the EUcompile a preliminary dam-age and needs assessmentreport for Lebanon. Thereport was presented at therecent donors' conferenceheld recently in Stockholm.

The images reveal that insouthern Lebanon 1,489buildings, 535 road sections,21 of the 29 bridges over the Litani River and 545 culti-

vated fields were eitherdestroyed or damaged.

In Beirut 326 residentialbuildings have been dam-aged or destroyed in thesouthern suburbs, alongwith all the runways ofBeirut airport and six strate-gic highway sections.

According to the report,the damage observed to theroads means access to impor-tant towns, services such ashospitals as well as cultivat-ed fields may be disrupted.The report also points outthat the satellite images onlyshow damage to buildingsthat is visible from overhead;in areas where ground bat-tles took place, considerablelateral damage to buildingsis also likely.

JRC and EUSC will continueto support the reconstructioneffort by establishing a spa-tial data infrastructure toallow for a more detailedassessment of the damages.

SAUDI ARABIA

SatelliteNavigationsystem to controlair trafficSaudi Arabia is planning tochange its civil aviation nav-igation system from groundbased to satellite based inphases.

According to MuhammadAl-Salimi, Director of air cor-ridors at General Authorityfor Civil Aviation (GACA), thenew system will be imple-mented partially at thisstage, as the total shifting tothe new international navi-gation system requires timeand should pass through dif-ferent phases.

Al-Salimi said the King-dom would enter into seriousnegotiations with a numberof countries under theumbrella of the InternationalCivil Aviation Authority toset out laws on the use ofsatellites for air navigation.

He said the Kingdom

would participate in theactivities of the InternationalCivil Aviation Organizationto develop and modernizecivil aviation systems, setout new regulations, andmodernize the managementof air traffic. Al-Salimi made this statement whileaddressing a meeting of theworking group to implementfuture navigation systems.The meeting was organizedby the GACA.

The shift from ground-based system to satellite-based requires qualifiedmanpower. The GACA willconduct intensive trainingcourses for its air traffic con-trol staff in satellite and digi-tal communication.He saidthe authority was currentlyapplying satellite communi-cation in some airlines. Theobjective is to help airlinessave time by reducing flightduration. This will alsoincrease air traffic andattract foreign airline com-panies, he explained.

Opening the meeting,GACA President Abdullah Al-Rehaimy said he was lookingforward to setting out mech-anisms that help Arab civilaviation administrations andairline companies to set upair corridors to provide air-link to aircraft equipped withFANS1A satellite air naviga-tion systems in Arab skies.

"Arab countries will bene-fit a lot by applying thismodern air navigation sys-tem in terms of economicand operational aspects andthe benefit will reflect direct-ly on air navigation service

providers as well as airlinesand other users," Al-Rehaimysaid.

Spelling out the benefits,he said direct use of air corri-dors would help save fuel,reduce the time for flight,increase air corridor capacity,help open new air corridorsand thus help increase airtraffic and financial returnsof Arab aviation authori-ties."It will also reduce thework of aviation controlstaff; achieve more efficiencyin communication betweenair control staff and pilot asthey will use digital datainstead of sound data. Thiswill also lead to improvingaviation security and safety,"he added.

Al-Salimi said the meetingwas aimed at promotingcoordination between aircontrol offices in Arab coun-tries in preparation to applythe new satellite system. Hesaid total reliance on thesatellite air navigation system would be achieved by2015.

Managing waterresourcesAs many water basins inYemen are facing watershortages due to changingclimatic conditions and over-use of ground waters, a needto develop and properlymanage available waterresources is being felt.

Considerable investmentsare allocated for constructingand rehabilitating waterstorage structures, toenhance ground water dis-charge, for expand irrigatedareas, and providing waterfor other uses.

To understand the effect ofdams on water status in giv-en water basin, various inves-tigations are required fordetermining surface waterand groundwater hydrology,

and subsequently advisingproper water resource man-agement strategies.

In a study of Sawan water-shed, which is located inSana'a basin, the effect ofthree small dams on shallowgroundwater discharge wasobserved. To study the effectof dams on groundwater dis-charge, static water levels ina number of open wells wasobserved in 2000 and 2001.

Static water level (SWL) ofwells near Mukhtan, Konaz-er, Beryan dams were signifi-cantly affected by the dis-tance from the dams. TheSWL of wells closer toMukhtan dam was 9 m whileSWL of well at distances ofabout 5.7 Km from the damwas 22.6 m. In the case ofBeryan dam, SWL were 7.9 mand 11.7m for wells at dis-tances 0.3 km and 6.1 kmfrom the dam, respectively,while SWL was found at 9 min wells near Konazer damand 22.3m in wells at 4.5 Kmfrom the dam. This indicatesthe presence of groundwaterdischarge, especially in theareas near the dams.

This study recommendsdocumenting hydroclimaticdata in order to establish aninformation database formajor watersheds, and tocarry out comprehensivestudies and investigations onthe effects of dams. Anemphasis is required to uti-lize mathematical models,GIS and other programs inthe Rapid Risk Assessmentprogram of watershed anddams.

ISRO gets contractto launch 16 nanosatellitesAround September 2007,India's rocket Polar SatelliteLaunch Vehicle (PSLV) willcarry a 100 kg capsule as anadditional passenger intospace. The capsule willunfurl a series of 16 nanosatellites that weighbetween one kg and five kg.

The University of Toronto,Canada, leads a team of aca-demic institutions thatwould build these satellites,designed to conduct researchon outer space, includingmicro-gravity experiments.It has contracted out thelaunch to the Indian SpaceResearch Organisation(ISRO). Nano satellites weighless than 10 kg and multiplesatellites work together as anetwork in space. In somecases, these formations ofnano satellites are connectedto a bigger satellite, calledthe mother, for communica-tion purposes.

The PSLV rocket has piggy-backed micro satellites thatweigh up to 100 kg to space,but this would be India's firstexperience in launchingnano satellites. "We haveseveral small satellites fromuniversities in India andabroad that will be launchedover the next few years," anofficial said.

ISRO will loft a 50 kgIndonesian remote sensingsatellite with Cartosat-2, thehome-grown one-metre reso-lution remote sensing satel-lite, when the PSLV islaunched next month. In thepast, India's rockets have car-ried several micro satellitesweighing less than 60 kg,including the Korean KIT-SAT-3, German DLR-TUBSAT,BIRD of Germany and PROBAof Belgium, into their intend-ed orbits.

Global studyshows benefits oflocationintelligenceAccording to a survey con-ducted by MapInfo Corpora-tion, a provider of locationintelligence solutions, andBusinessWeek Research Services, 64 percent of business executives believethat location intelligence canimprove business processes,and 21 percent are planningto investigate it in the next year.

1,700 business executivesparticipated in this interna-tional study to gauge the rolethat technology can play indelivering powerful, busi-ness-relevant location intelli-gence to leading organiza-tions.

80 percent of data that anorganization uses to makekey decisions to improve itsefficiency, effectiveness andprofitability has a location-based component.

Optimizing informationsuch as a ZIP code, telephonenumber or address enablescompanies to answer criticalquestions such as: Where canI find more of my best cus-tomers? Where are competi-tors impacting my business?Where is my newest productor service most valuable?

For instance, MasterCardWorldwide relies on theMapInfo Envinsa locationintelligence platform to pow-er its worldwide ATM Locatorservice. Envinsa replacedMasterCard's previous onlineand phone ATM Locator serv-ices with a more integratedplatform for deploying loca-tion technology across theentire organization. As aresult, MasterCard was ableto reduce costs and provideenhanced customer serviceto millions of customers.

Satellite pics helpclaiming highercompensationRoughly 140 kilometre fromMumbai, the capital city ofIndian state of Maharashtra,farmers are turning to tech-nology to fight for theirrights.

Four months ago, the farm-ers of Pen taluka in Raigaddistrict were told the stategovernment was acquiringtheir land to help build the25,000 acre Maha MumbaiSpecial Economic Zone (SEZ).

That's when an activist ofthe SEZ Hatao Virodh Samiti,Arun Shivkar, logged on toGoogle Earth. "We usedGoogle technology to proveto the authorities that theland is fertile," said Shivkar.

Shivkar says initially stateauthorities claimed that onlya small portion of the ear-marked land is fertile andthat some parts of it is sub-merged by salty creek water,meaning lower compensa-tion for the farmers.

But Google Earth has cometo the rescue and its satellitepictures clearly indicate cropareas. This has helped farm-ers back their claims for high-er compensation. The tech-nology has also brought

together farmers from 45 vil-lages to put up a commonfront and protest the acquisi-tion of their land.

The ingenious ways inwhich farmers in Maharash-tra are using Google Earth tofight for their rights is per-haps a testament to howtechnology is truly flatteningthe world.

Satelliteimageries reveal,green means rain Scientists from Natural Envi-ronment Research Council(NERC)-funded Climate andLand Surface InteractionsCentre (CLASSIC) have foundthat the presence of greenvegetation has a major influ-ence on the amount of rainthat falls in the Sahel regionof Africa, south of the Saharadesert.

Rains at the start of thegrowing season cause vege-tation growth. This encour-ages a feedback loop as the greener the vegetationbecomes, the greater theamount of rain that falls.

This important newresearch could help us to pre-dict future droughts inAfrica. The research can beused to aid regional andinternational forecasts forrain-starved regions.

Using satellite technology,Dr Sietse Los and colleaguesat CLASSIC worked withNASA to develop a datasetcovering 18 years of vegeta-tion greenness records. Theycombined these records withrainfall data in the region

over the same period -- from1982 to1999.

The resulting analysesshow, for the first time, thatrainfall amounts varybetween 10% and 30% morewhen the land is green, anddecreases by a similaramount when conditions aredry and there is little greenvegetation growing. Theresearch was published inGeophysical Research Letters(USA), August 2006.

New cropinsurance toolsmade availableThe US Department of Agri-culture has made availabletwo new risk managementtools for pasture, rangelandand forage in a select groupof states for a pilot program,beginning with the 2007crop year.

The rainfall index insur-ance program and the vege-tation index insurance pro-gram, offered by USDA's RiskManagement Agency, willallow livestock producers topurchase insurance protec-tion for losses of forage.

"These new insurancestools will help farmers andranchers, especially withoperations located indrought-impacted areas, toimprove their risk manage-ment capabilities," said U.S.Agriculture Secretary MikeJohanns.

The rainfall index programwill be tested in 220 countiesin Colorado, Idaho, Pennsyl-vania, South Carolina, NorthDakota and Texas. The vege-

tation index insurance pro-gram will be tested in 110counties. And is based onsatellite imagery as a meansto measure expected produc-tion losses.

NASA probesorigin ofhurricanesThe NASA- backed missionhas set up three radars one inlandlocked Niger's capitalNiamey, the one in Kawsaraon the Senegalese coast, andone on the Cape VerdeIslands and is also flying

planes into the centre of thedepressions. The objective isto understand how hurri-canes that slam into thesoutheastern United Statesand the Caribbean areformed in West Africa beforethey go bowling across theAtlantic.

The data provided by theseradars will enable scientistsfor the first time to mapmore fully the atmosphericconditions as Atlantic hurri-

canes are born and throughtheir life cycle. Previousattempts to understand thephenomenon have relied onsatellite data, which canshow what is happening ontop of clouds but not insidethem.

The study could help forecasters better predictdevastating hurricanes likeKatrina.

"This is the first time withaircraft, with radars on theground, that we can lookinside these disturbances.And once you understandwhat's happening inside youhave a better chance of pre-dicting," said Greg Jenkins, aspecialist in tropical meteor-ology from Howard Universi-ty, Washington.

Paul Kucera from the Uni-versity of North Dakota, whohas studied weather patternsin Papua New Guinea, theSouth China Sea and aroundthe Amazon, said, "If we cancapture the atmospheric con-ditions of the storm, thestorm structure, how theyevolve over the African conti-nent and just off the coast,our objective is to distinguishbetween those that staytogether and those that dissi-pate."

Starting November, Beijingwill investigate and prose-cute major cases of illegal useof land, especially those thatviolate government plans ornational industrial policiesand those that infringe onfarmers' legitimate rights astold by An Jiasheng, Directorof the Beijing MunicipalBureau of Land andResources.

Authorities can now availthemselves of satelliteremote sensing technologiesto discover and prevent theillegal use of land, An told aconference.

The Chinese central gov-ernment tightened controlover land after the economygrew 10.9 percent in the firsthalf, promising to penalizelocal officials who fail to stopor investigate land use trans-gressions.

The Ministry of Land andResources laid down in arecent circular that local gov-ernments must not approvemore land for construction in2007 than they did in 2006.

"The principle is tostrengthen macro-economiccontrol and use landresources economically," itsaid, adding that localitiesmust make use of land "sci-entifically and rationally" to protect farm land and land for other agricultural purposes.

It urged localities to "actconjointly" with the StateCouncil in implementingmacro-economic control poli-cies and prevent runawayfixed-asset investment.

Japan launchesspy satelliteJapan launched its thirdintelligence-gathering satel-lite on September 11, enhanc-ing its ability to monitorneighbouring North Koreatwo months after Pyongyang

shocked the region with abarrage of missile tests.

Japan's space agency,JAXA, launched the opticalsatellite from the southernisland of Tanegashima,adding to a pair of satellitesthat were fired into orbit inMarch 2003. Two other satel-lites were lost when a rocketfailed in November that year.

A further radar satellite isset to be launched later thisyear, completing the set offour. The optical satellite willbe able to differentiateobjects a meter (yard) ormore in diameter, althoughthis level of resolution is faroutclassed by U.S. militarysatellites.

A ban on defense use ofspace dating from the 1960shas hampered Japan's abilityto develop high-tech hard-ware.

With two similar satellitesin orbit, the Japanese govern-ment will be able to monitorany point on Earth once aday, an official at Japan'sCabinet Satellite IntelligenceCenter said.

Japan planned its spysatellite program followingNorth Korea's 1998 launch ofa ballistic missile that flewover Japan and landed in thePacific Ocean.

On July 5, Pyongyanglaunched another volley ofmissiles, sparking uneaseacross the region. NorthKorea reacted angrily toSouth Korea's July launch ofthe Arirang-2 surveillancesatellite capable of monitor-ing military movements.

Decreasing Water Levelsin Egypt's Toshka LakesWhen: March 2001 - December 2005

Where: Egypt

What: This pair of images documentsrecent drops in water levels in the ToshkaLakes region of Egypt. The Toshka Lakesand the New Valley surrounding the lakesconstitute a major Egyptian project toclaim a huge area of desert for agricultureand industry by diverting Nile River waterfrom Lake Nasser. The initial floodingoccurred in the late 1990s, when Lake Nass-er water levels were at an all-time high.The flooded regions of the Toshka Lakeswest of Lake Nasser have decreased greatlyover the years, exposing the former dunefields (dunes appear as islands in the lakeand along the shoreline of the top image),and leaving a "bath-tub ring" of wetlands(dark region) surrounding the lake shore-lines. As both the drought and develop-ment continue, this region of Egypt is sureto change.

Tarbela Dam, Indus River Basin, PakistanWhen: September 6, 2002

Where: Tarbela Dam, North-West of Islamabad

What: The Indus River basin extends from theHimalaya Mountains that form the northeasternboundary of Pakistan to the alluvial plains of Sindhnear the Arabian Sea coastline. With a volume of142,000,000 cubic meters, the Tarbela Dam is thelargest earth and rock fill dam in the world and stands147 meters above the Indus riverbed.

Tarbela Dam is part of the Indus Basin Project,designed primarily for water storage rather than pow-er generation, the dam was completed in 1977.Whilethe dam has fulfilled its purpose in storing water foragricultural use in Pakistan, there have been environ-mental consequences to the Indus river delta. Reduc-tion of seasonal flooding and reduced water flows tothe delta has decreased mangrove stands and theabundance of some fish species.

Acity is usually the centre ofeducation, trade, industry, cul-

tural life, government, etc. It offers a varietyof opportunities, which always has attractedpeople.

The increase in population or public needs inevitably leads toincrease in both complexity of tasks that have to be plannedand the information that has to be processed. One of such com-plex task is digging the ground safely, without any disruptionsto utility services. This application is primarily developed,according to the needs of city Madinah. Al Madinah AlMunawarah also known as "City of Light" is second holiest cityin the history of Islam attracting in numerous people as tourists& pilgrimage from the world throughout the year.

Due to increase in demand the city is continuously expandingresults in designing of new utility elements.

The study area in planning affairs requires Georeferencedinformation while digging any site. In order to look after the

safety of utility elements already passing under the digging siteand to ensure the future planning of network. It is necessary tocommunicate with all utility departments before digging the site.

In the earlier days, any digging site had to be mapped on paperand get approval from each utility department. This procedurewas not only time consuming but also insecure. It has lot of dis-advantages as compared to current online digging system.

Developments in both communications and computer haveopened up new horizons to deal with such complex issues. Visu-alizations on web electronic market is considered as a newinformation revolution and tremendous amount of money andmanpower have been invested in web based commerce sys-tems. Integration of such technologies with GIS has resulted inthe development new applications, the current developed sys-tem called Digging Information System can be held as an exam-ple.

The application has two major divisions based on access toapplication i.e. access by Internet and access by Intranet. Thereare about six utility departments (can be called external depart-ments) that access this application through Internet. The Inter-net system works on Client/Server concept that involves split-ting the application into tasks between server and client. Thisapplication has three components a Client, a Server and a Net-

DIGGING INFORMATION SYSTEM

The paper describes a web based GIS application used to share crucial infoemation amongdifferent utility departments required for carrying out their digging operations.

work (Hall 1994). This application holds acolumn for seventh department called asAmana. Amana department is the repre-sentative of other six departments (sayinternal departments), which works onIntranet.

The above system starts with login pageand to authenticate users and their roles.Basically there are two types of rolesplayed in action. One is contractor whoinitiates the new dig- order for a utilitypurpose and the other is Departmentwhich approves or rejects the order.

Initially every new dig-order will be indormant stage, wherein all departmentscannot see the order in the list of theirpending orders except the representativedepartment or owner department. Dor-mant orders are made active by the repre-sentative utility department after check-ing some validity conditions like contrac-tor doesn't hold any old penalties, diggingpath is rightly coordinated on ground, etc.Dormant orders are made active with afunction called 'ShowToAll' available onapplication, Once the order is madeactive, it will be populated to all screens.All departments are subject to give theirdecision within 3 working days for thisactive order, which they can see in theirlist of pending orders.

Departments entitled to give their deci-sion can use the supportive functions onapplication like viewing the digging pathon Map with applicable spatial layers andquickbird image as background, orderattributes and its coordinates on newdynamic pages, printable format of orderwith its location on map and importantdetails etc.

The details of the order are hyperlinkedon dynamic pages. Moreover the decisionon each order by each department canalso be viewed.

All the external six departments givetheir decisions through Internet but thedecision from seventh department(Amana) is result of second part of appli-cation called "Internal Application",

which is accessedthrough Intranet,and is developedwith Oracle formand MapBasic pro-gramming. Sixinternal depart-ments use this partand dependingupon their deci-sions Amana giveits decision. If anyof six internaldepartments rejectthe order thenAmana concludesits decision asrejection on exter-nal application(accessible thoughInternet). Thedepartment'snames and reasonsfor their rejectioncan be viewed byexternal depart-ments on hyperlinked page in column listof Amana department.

TOOLSDigging Information System has two divisions working on common Oracle database, they are external andinternal.

The External part (Internet application)can be divided into two parts they areMapping and Transaction part. MappingPart has been programmed using MapXcomponents of MapXtreme 3.0. The Spa-tial layers are available as Tab (*.Tab) orWorkspace (*.wor), which are then con-verted into Geoset (*.gst).

Transaction part holds complete busi-ness logic written in Visual Basic 6.0 andconverted into dll (as Com object). Theobject performs communication withdatabase in Oracle for data manipulationlike creating, editing, adding, deletingrecords etc.

DEPARTMENTS AND THEIRDECISIONSDecision to any digging project is givenby 14 active departments. Seven of themare called Internal departments as theyare located inside the Madinah Muncipal-ity. They are Study & Supervision, Opera-tion & Maintenance, Gardening, Valley &flowage, Execution & Development, andBaladiyat Subsidiary. The above six inter-nal departments have been divided onthe based of their relation and theirdependency on Madinah municipality.

The other seven are called ExternalDepartments, which require internet toaccess the Digging System, they areWater, Electricity, Telecom, Traffic, Trans-port and Civil Defence. Since the internaldepartment are local to Madinah Munici-pality, an Intranet based application isdeveloped to carry out the process, whichis called as Internal System. For externaldepartments an Internet based applica-

tion is developed called as External Sys-tem.

Both the systems have one commondatabase. If any one of the 14 depart-ments rejects the dig order then order ismeant to be rejected.

The combined decision from internaldepartments is stored in a single depart-ment file called Amana and is represent-ed in External website.

Therefore, the external department willbe able to view the decision from internalsystem as well as from the other externaldepartments on the Digging InformationSystem with internet access. This makesthe license issuing authority to view thedecisions from all departments and theirstatus at the same time for each andevery order.

NEW ORDER This is a secured application as users withonly valid login identities can access it.Applications hold different privileges forcontractors and for users from eachdepartment. There are different func-tionalities which a user is privileged toaccess like creating new dig order, view-

ing own orders,viewing otherdepartmentorders, approvingor rejecting anorder etc.

For every newdigging project tobe carried out forany utility pur-pose, a contractorshall supply thedetails on fields inNew-Order formto concerned utili-ty departmentthrough theonline system.The details of theorder are saved inOracle database

and can be accessed by both the external(internet) and internal (intranet) parts ofdigging application, as they both sharethe database.

A new dig-order contains fields like con-tractor name, order number, depth,width, date, stage, coordinates of the dig-ging path etc. Coordinates shall be sub-mitted (simply paste in the text area ofNew-Order form) in a unique format asshown below. X and Y are the projectedcoordinates on ground and explanationfor section is followed.

Section and Stages

Coordinates which are submitted onlinehas x, y and section Here, change of sec-tion represents the change in the conti-nuity of line. Points of the same sectionnumber are connected to each other butnext point having different section num-ber is considered as new first point and

will connect all those points having thesame section number. Hence any discon-tinuity or turning in the digging path canbe mapped easily. Another important fac-tor to be considered is that any single dig-ging project can have multiple stages.Each stage could differ with its location ofdigging path, geometry and start date,which means same order number canhave multiple digging stages. So, everynew order is created using three primarykeys they are order number, date andstage.

SUPPORTING FUNCTIONALI-TIES OF ONLINE SYSTEM:

Dig order check by owner departmentUtility department will then fill the orderdetails from the Online Digging system.Once the order is submitted, it can beviewed in the list of orders called fromfunction 'ViewMyOrders'. But this neworder will not be shown to other depart-ments since it will be in test status. Under'test' status, the order is private to ownerdepartment and also represented with atest symbol. Test status is meant for thedepartment to check the validity of orderdetails, whether contractor owes anypenalty or examine it on map with func-tion 'ShowOrderOnMap' and get con-firmed to send it into the cycle where allother departments will give their deci-sion to approve or reject. The ownerdepartment then clicks on function 'ShowTo All Depts', which then changes its sta-tus as well as symbol from Test to Pend-ing. Pending symbol is shown in the col-umn for other departments and in row ofthat particular order number.

This Function plays an important role indecision-making as it involves map. Nosooner than a new dig-order is submittedonline, other department would be ableto view the details of that order in textformat and on map as shown in the figure 3 and 4.

The ordersin this page are waiting or pending forthe decision (Approval or Reject) from thedepartment who is logged in. This Win-dow also contains commands to approveor reject any dig-Order. The user shallselect the dig order from the list and clickson reject command there after a newdecision will open as shown in Fig.5 con-taining fields for details of rejection oracception. Coordinates of each order aresaved in oracle database with its ordernumber. These coordinates are drawn ona Temp layer created using MapXtremeand overlay on other spatial layers withred and thick line width. Followed byzoom to order where user can zoom in orzoom out or pan or zoom to full extent.

CONCLUSIONSDigging Information Systems has beenimplemented successfully and found tobe very instrumental in solving problemsfaced due to a lot of paper work. It savestime, and provides security and assur-ance. Improvements can be made infuture like:

Report creation for each department todisplay graph containing informationsuch as number of accepted orders, num-bers of pending orders.

Automatic SMS or email facility to pro-vide communication among all thedepartments.

Improvements in the mapping part

with commands to spatial queries andthematic query on digging orders.

Introducing VRML (Virtual Reality Mod-elling Language) for 3D Modelling of digorder path in order to understand thedepth information more precisely.

The socio-economic developmentof any country is based on land

and water resources. Due to increase in pop-ulation, these resources are over stretchedoften leading to resource depletion.

There is evidence to show that a majority of world over landresources is under 0 and is undergoing degradation at an unac-ceptable rate (Kharin et al 1999, Harahsheh 2001) A recentresearch study on Middle East desertification shows the gravityof land degradation problems in all levels. It concluded that thewhole of Middle East is subject to degradation, mainly by vege-tation degradation process, where 40% of study area is severelyaffected by vegetation degradation, followed by soil degrada-tion process (27% severe wind erosion). Without doubt theseresults show the gravity of land degradation problem in thestudy area (Harahsheh, 2001). There is therefore need to pru-

dently manage these delicate resources. The situation in DubaiEmirates (UAE) is no different. Moreover, Dubai being located inan arid desert belt, it is highly sensitive to a number of criticalenvironmental issues. Soil is one such important issue, as it is anon-renewable natural resource.

Soil is in-fact at the heart of terrestrial ecology and is vital toour existence. Information on soils with regard to their nature,extent and spatial distribution along with their potential andlimitations is required for a variety of uses, namely agriculturaldevelopment, engineering, sanitary, recreation, aesthetic, etc. Inaddition, such information is also required for modeling andenvironmental impact analysis. Therefore, it is imperative thatwe manage and conserve soils to meet the growing need forfood, fodder, fiber and fuel. For this purpose, we must have anin-depth knowledge about different soils, their morphology,characterization, behaviour, kind and degree of problem andtheir extent and distribution on the landscape.

Dubai municipality has taken the initiative to use the remotesensing technology for thematic mapping of UAE area usingsatellite imagery including soil mapping. Integration of themat-ic maps, soil and others are used for better and optimal utiliza-tion of various land and water resources and can be used formany applications like demarcation of potential ground waterzone and for site selection processes etc.

OBJECTIVEThe objective of this study is to generatethematic geodatabase information onsoil resources of UAE.

The soil map of Dubai and Hatta wasprepared at 1: 25,000 scale using the Indi-an Remote sensing Satellite (IRS-ID) Lin-ear Imaging Self Scanning Sensor (LISS IV)data. The soils of the study area were clas-sified as per USDA (2003) up to soil seriesand their association level.

STUDY AREAThe project area covers the UAE, an areaof 4000 sq km (Figure1).

The overall climate of the Emirates issubtropical, warm and arid. Air tempera-tures range between 350 to 500 C fromMay to October during the middle of theday and between 200 to 350 at mid-dayduring the winter months.

The average annual rainfall of the Emi-rate which falls mostly during wintermonths is about 100 mm. The rainfall,however, is very erratic and variesextremely both from year to year andplace to place.

Some moisture also condenses in theform of fog and dew, especially in thecoastal belts. Strong winds and sandstorms are also of common occurrencethroughout the Emirate. They are espe-cially more frequent and severe duringsummer months. Sand dunes are thedominant feature of the landscape overmost of the Emirate.

INPUT DATAIn the presentstudy for generat-ing base lineinformation onsoil resources ofDubai and Hattaarea the IndianRemote sensingSatellite (IRS-ID)Linear ImagingSelf Scanning Sen-sor (LISS-III & LISSIV) data havebeen used. Ortho-rectified IKONOSdata is providedby Dubai Munici-pality for Geo-ref-erencing of IRS -P6, LISS IV dataBesides the satel-lite data the basemaps prepared by the project team, pub-lished soil maps, topographic maps, cli-matic data etc. are also collected and usedas collateral data.

METHODOLOGYEssentially soil survey is a study andmapping of soils in the field. It is the sys-tematic examination, description, classi-fication and mapping of soils of an areaand it comprises of a group of interlinkedoperations involving

• Preliminary visual interpretation of satel-lite data

• Fieldwork to study important character-istics of soils and associated land charac-teristics such as landform, natural vegeta-tion, slope etc.

• Laboratory analysis to support and sup-plement the field observations.

• Correlation and classification of soilsinto defined taxonomic units.

• Mapping of soils - that is establishingand drawing soil boundaries of differentkinds of soils on standard geographicalbase map.The over all methodology for mapping

the soils is shown in Figure 3.

PRELIMINARY VISUAL INTERPRETATIONThe steps involved in pre-field interpreta-tion is monoscopic visual interpretationof Indian Remote Sensing Satellite (IRS)ID LISS-III and IRS P6 LISS IV data at 1:25,000 scale based on the standardremote sensing techniques using imagecharacteristics such as tone, texture, pat-tern, shape, size, association etc. in con-junction with the collateral informationavailable in the form of published mapsand reports. A tentative interpretationkey in terms of lithology, physiography,land use/land cover, erosion/salinity/alkalinity hazards and image elementswas developed.

FIELD WORKA field visit was undertaken in Dubai andHatta study areas, to study importantcharacteristics of soils and associatedland features for mapping soils.

The first step in soil survey begins withgeneral fact finding exercise through areconnaissance of the area, so a prelimi-

nary study on the landform, geology, cli-mate and vegetation of the study areawas undertaken. For carrying out thefieldwork the scientists traversed thestudy area with a base map, satelliteimagery for the first three days. Duringthe traverse, the scientists noted the vari-ations in landforms and associated soils.The ground features were also correlatedwith the image features.

Soil profile studies and sample collectionThe detailed soil-site study was undertak-en in each soil-mapping unit by generaltraversing and by collecting surface soil,minipit and soil profile observations atintervals depending on soil variability.The soil profiles/pedons (A vertical cutfrom the surface down to the hard rockfrom which the soil is formed gives thesoil profile and in the profile several suc-cessive characteristic layers can be identi-fied. A profile pit with exposed verticalface of approximately 1 meter across toan appropriate depth (nearly 1 m) was

satisfactory for most soils. Each layer(horizons) was studied for various mor-phological features such as colour, tex-ture, structure, consistency etc. The fre-quent profile sampling enabled to deter-mine the depth of various horizons andalso the horizons of gains (alluvial) andlosses (eluvial). Sometimes, by merelylooking at the surface soil and at othertimes, by rubbing the surface soilbetween thumb and fingers (to deter-mine soil texture) reflects soil properties.

A detailed description of each profilewas noted down on the pro-forma. Thepro-forma includes many parameters,which were collected. This includes, Loca-tion of the soil profile in terms of latitudeand longitude, Physiographic unit, Parentmaterial / Geology, Slope (%),Soil charac-teristics, Soil depth, Soil texture, Consis-tency and much more. Also Efferves-cence test was performed by squirting10% HCl on the soil to determine the freecarbonates.

In Dubai and Hatta area 129 soil profileswere excavated and large number of

observations were also taken.In total 333 soil samples werecollected.

LABORATORY ANALYSIS

Physical & Chemical PropertiesParticle Size Analysis - was car-ried out by the InternationalPipette Method (Piper, 1966)using Sodium Hexametaphos-phate as a dispersing agent.The textural class was deter-mined using the USDA textur-al triangle. Chemical analysisincluding, Soil Reaction (pH),Electrical conductivity (EC),Organic Carbon (OC), CalciumCarbonate (CaCO3) and CationExchange Capacity (CEC).

POST FIELD INTERPRETATIONPreliminary interpreted soil boundariesfrom IRS-P6 were modified using fieldinformation and final thematic detailswere transferred on to the base map.Finally the soils were classified in thelight of soil morphology features, soilphysical and chemical properties asdescribed in soil survey procedure (USDA,2003). Thus, the landscape map was con-verted into soil escape map in terms ofsoil series and / associations thereof.Based on the variations in the soil andsite characteristics 26 soil series havebeen identified in Dubai area and 13 seriesin Hatta area.

DESCRIPTION OF SOILS OF DUBAIThe soils are generally coarse, sandy,highly calcareous and undeveloped. Theyare deficient in organic matter. Soils inthe coastal belt and low-lying areas anddepressions are highly saline. The soils inthe interior of the desert are either salineor sodic. The major Landscapes identified

In Hatta area the major Physiographyunits identified are structural valleyregion, piedmont area, residual hills,denudational hills ( Periodite/ dunite/gabbro),denudational hills ( limestone/dolomite/marble) and structural hills(periodite/ dunite / gabbrointerbedded),

The soil temperature regime of Dubaiand Hatta is hyperthermic, which can beinferred from the climatic data of Dubai.The soil moisture regime is aridic / Torric.In general all the soils of Dubai are cal-careous. As the study area falls under aridregion the soils occurring in these areaswill normally have an aridic (torric) mois-ture regime. On analysis of all the soilsamples collected during the groundtruth, it can be inferred that all the soils ofDubai and Hatta area are calcareous. Theother features of the soils occurring in thestudy area are also discussed separately.

LAND CAPABILITYSoil resources maps, as mentioned earlier,provide information on location, spatialextent and physico- chemical characteris-tics of soils.

Land capability classification is an inter-pretive grouping of soils mainly based on1) the inherent soil characteristics ii)external land features and iii) environ-mental factors that limit the uses of land.Scientific soil surveys provide informa-tion on the first two aspects. Effective soil

depth, soil texture, permeability of subsoil and sub-stratum, available moisturecapacity, reaction, inherent fertility,organic matter content, salinity and/ sod-icity are some of the important inherentsoil characteristics. Amongst importantland features are natural surfacedrainage, slope, erosion, wetness, andgravelliness. Besides, the aforesaid fac-tors, climate does play a very significantrole in deciding the potential of a givenpiece of land for sustainable develop-ment. In the land capability classificationthere are eight classes. Classes I, II and IIIinclude the land suited for regular culti-vation. Class IV land is fairly good for cul-tivation but its safe use for cropping isvery limited by natural features such asslope, erosion, unfavourable soil charac-teristics and adverse climate. Classes V,

VI, VII are not suited for any cultivationbut may be used for grazing or forestry,according to adaptability. Class VIII landis suited only for wildlife or recreation.

Nowadays, individuals, universities,organizations and companies use

the Web as a main infrastructure to publishspatial information, offer or consume GISservices and in some rare cases to conduct acomplicated GIS processing.

Due to the high potential of Internet and Web, many differentWeb mapping software packages have been provided by differ-ent GIS vendors. But each Web mapping software, utilize differ-ent technologies, which are not able to interact and interoperatewith each other directly. For this reason, service on a particularGIS server can only be accessed by its own clients and otherclients (clients of other GIS servers) cannot access services ofthat server.

On the other hand, application-integration is not supportedwith current Web mapping software. Today, GIS developerscan't combine specific services from different Web mappingsoftware, and use them as building block of an integrated GISapplication. These problems arise because of this fact that, Inter-

net-based applications need to be able to interact with otherInternet-based applications as easily as interactions betweenWeb browsers and Web servers. But the essentially text-basedWeb does not support software interaction very well.

A more efficient method is needed to allow applications, inter-act directly with other applications to automatically and with-out human intervention, executing instructions that would oth-erwise have to be entered manually through Web browser(Cerami 2002). But the main barrier in front of application-to-application interactions is the interoperability. The followingsection will describe spatial interoperability and differentaspects and resources of this problem.

SPATIAL INTEROPERABILITYThe most important problem associated with GIS systems isnon-Interoperability of these systems. Based on OGC's referencemodel (OGC 2003) interoperability refers to "capability to com-municate, execute programs, or transfer data among variousfunctional units in a manner that requires the user to have littleor no knowledge of the unique characteristics of those units".

According to OGC 2004 and the mentioned definition, fivesources for spatial non-interoperability could be identified:

• Different types of geoprocessing systems (Vector, Raster, CAD,etc. ) produce very different types of data.

• Different vendors' geoprocessing systems use internal data for-

Potential of Using Web Services in Distributed GIS Applications

This paper intends to evaluate the key problems associated with present GIS services i.enon interoperability, and discusses how web services can overcome the same.

mats and produce data in formats that aredifferent and in most cases proprietary.

• Different vendors' systems use propri-etary software access methods with pro-prietary interfaces that restrict opportuni-ties for network inter-process communi-cation between systems.

• Different data producers, even if usingthe same type of system from the samevendor, do not, name spatial features inthe same way.

• Different data producers, if they providemetadata, do not, structure their metadatain standard schemas that enable effectivemetadata searches.

In this list the items one, two and threeare the causes of technical non-interoper-ability and items number four and fiveare the causes of semantic non-interoper-ability. As GIS community believes, solu-tion for semantic non-interoperability isconsensus development of interoperablestandards and specifications.

In this context, OGC plays a major roleby setting the Industry standards for GISservices. Generally the main goal of OGCis to promote the widespread use of inter-operable GIS services throughout theinformation infrastructure.

In GIS community solutions for over-coming technical non-interoperabilityhave changed with the development ofnew technologies in IT world. In IT world,the best solution for providing interoper-ability among heterogeneous systems indistributed, decentralized environmentsare Web services technologies (Volter etal 2005).

Following sections will briefly introducethe concepts of Web services and GIS Webservice as well as how Web services canovercome the mentioned problem.

Service Oriented Architecture and Webservices Technologies

The Web as it exists today is intendedfor human consumption. Consequently,data is presented in a form that ishuman-readable, but this form of repre-sentation is error prone and difficult forapplications to examine, extract and useboth, automatically and programmatical-ly. So there is a need for application-to-

application com-munication andthis is the idea ofapplication-centricWeb rather thanhuman-centricWeb (The Web as itworks today).

An application-centric Web is notnew concept(Newcomer 2002).For many years,developers andprogrammers havecreated and used Common gate Interface(CGI) and CGI extension programs (suchas Java servlets modules, Active ServerPage (ASP), Jave Server Page (JSP) andCold Fusion Web applications and so on)for communicating between differentapplications. But most of these systemswere used as a part of tightly coupledplatform and as a result they can't offerservice to other business solutions.

Promising technology for providingcross platform application-to-applicationcommunication is Web services technolo-gies. In fact, Web services are implemen-tation of a conceptual architecture, whichis called Service Oriented Architecture(SOA). SOA is a conceptual architecturefor implementing

• Loosely Coupled

• Self-Describing

• Standard-based

• Dynamic discoverable

Services (Newcomer and Lomow, 2005).Also some IT experts state that SOA is

the next generation of Software imple-mentation which is emerged after dis-tributed technologies paradigm (Marksand Werrell, 2003).

In SOA, the central elements are servic-es. Service is a location on the networkthat has a machine-readable descriptionof the messages it receives and returns.

As illustrated in Figure 1, a SOA consists

of three primary roles and three primarytasks. Service provider, service requesterand service broker are distributed compu-tational Nodes on the network. Serviceprovider publishes its own service withservice broker. Service requester uses theservice broker to find desirable servicesand then binds to a service provider toinvoke the service.

The actual implementation of SOAusing open, standard and widely usedprotocols and technologies is called Webservices (Newcomer and Lomow 2005).

Web services are about delivering dis-tributed applications via programmableURLs (Amirian and Mansurian 2006).Web services are eXtensibe Markup Lan-guage (XML) applications mapped to pro-grams, objects, or databases or to compre-hensive business functions (Newcomer2002). Using an XML document in theform of a message, a program sends arequest to a Web service across the net-work, and optionally receives a reply alsoin the form of an XML document.

Web services are based on open stan-dards, so they can provide technical inter-operability in network environmentssuch as Web. These brand new technolo-gies can be created by using any softwareplatform, operating system, program-ming language and object model. Moreprecisely, Web Services are loosely cou-pled, self-describing services that are

accessed programmatically across a dis-tributed network, and exchange datausing vendor, platform, and languageneutral protocols (Marks and Werrell,2003).

Web services are implemented by usinga collection of standards. These stan-dards, when considered together, formwhat is widely referred to as the "Webservices stack.

According to Marks and Werrell (2003),Figure 2 illustrates the seven distinct lay-ers of the Web services stack, whichshould be read from bottom to top.

As illustrated, these 7 layers are groupedinto three distinct levels - each level indi-cates a level of maturity for the layers itcontains.

The enabling standards level containstwo layers: the network transport proto-cols and meta-language. The layers with-in the enabling standards level containwell-defined and accepted standards andprotocols that are widely used in Internetand Web such as HTTP and XML.

The evolving standards level containslayers for SOAP , WSDL , and UDDI . Collec-tively, these layers form the standards forimplementation of Web services.

SOAP is a lightweight, XML-based pro-tocol for exchanging information indecentralized, distributed environments.SOAP is used for messaging among vari-ous SOA's components in a Web servicesplatform. SOAP is platform independent

and also it can beused with variousNetwork Trans-port protocolssuch as FTP , HTTP,HTTPS, HTTP-R,and BEEP. WSDL isxml-based specifi-cation for describethe capabilities ofa service in a stan-dard and extensi-ble manner. UDDIis a set of specifi-

cations and APIs for registering, findingand discovering services.

As illustrated in Figure 3, these layersestablish an explicit mapping betweenelements of SOA as a conceptual andTechnology independent architectureand Web services as specific collection ofstandards, protocols and technologies.

In this case, service provider publish itsown service description using WSDL,then Requester take advantage of searchAPI's of UDDI to find appropriate servicesand finally, service requester bind to theservice provider using SOAP.

The last level of standards or emergingstandards level has the least well-definedcapabilities. This level represents pro-posed standards for QOS and businessprocess flow which are promoted by indi-vidual vendors such as Microsoft, IBM.

In the context of Web services eachservice has three main parts: Servicedescription, Executable agent, and themapping layer between two (Figure 4).

The machine-readable description- thatis a WSDL document- contains networkaddress for the service, the operation itsupports and other needed informationfor consume the service.

The executable agent is responsible for implementing the functionality ofservices.

The description is separated from theexecution environment using a mappinglayer.

The mapping layer is often implement-ed using proxies and skeleton (Newcomerand Lomow, 2005). This layer is responsi-ble for accepting the message, transform-ing the XML data to and from the nativeformat of executable agent and finallydispatching the data to the executableagent.

On account of separation between exe-cutable environment and description ofservice or separation between semanticand functionality of services in the Webservice world, Web services can be creat-ed by using any software platform, oper-ating system, programming languageand object model. So it is not a difficulttask for a developer to bridge heteroge-neous computing platforms such as J2EE,CORBA and .NET.

Following section will describe how WScan resolve the problem of non-interoper-ability in GIS world.

Potential of Using Web Service Tech-nologies in Distributed GIS Applications

Web services are fundamentally newplatform. This platform provides looselycoupled, standard based, self describableand dynamic discoverable services. Webservices considered as the best long rangesolution for non-interoperability prob-lem. They provide unprecedented flexi-bility and extensibility when comparedwith other distributed architectures suchas Distributed Component Object Model(DCOM) and Common Object RequestBroker Architecture (CORBA). Precisely

Web services technologies provide twomajor advantages over previous distrib-uted computing architectures (Newcom-er and Lomow 2005)

• Most existing distributed computingarchitectures include the communicationprotocol as part of their scope. In the oth-er words, they provide vendor specificaccess methods. With Web services thecommunication protocol is an open proto-col which is widely used over the Web(HTTP).

• In existing distributed computing archi-tectures, data types were specific to plat-forms, programming languages, middle-ware systems and DBMSs. Web servicesnicely resolve this problem by using uni-versal data type which is provided by XMLplatform.

Consequently this loosely coupledarchitecture provides a new and promis-ing solution for implementation of com-plex collaborative applications such as adistributed GIS services. In some ways,the integration of GIS and Web servicessimply means that GIS can be moreextensively implemented, and peoplewill be able to take mapping, data, andgeoprocessing services from manyservers and integrate them into a com-mon environment (ESRI 2003).

GIS Web services can be categorized asprocessing service and geodata service.The GIS processing services provide dif-ferent GIS functions and operators. TheGIS geodata services provide access to GISdata. On account of Peng and Tsou (2003),to increase data interoperability, a com-mon format of geospatial data could beprovided. GML (Geography Markup Lan-guage) could be such a common format.

GIS community can use SOAP as syn-chronous and asynchronous messagingprotocol for utilize processing services aswell as geodata services.

In GIS world for fully take advantage ofWeb service architecture, different GISservice providers must publish their serv-ices on the Internet and advertise itthrough public UDDI or a dedicated GISservice registry (which might be providedby collaboration of members of GIS com-

munity). At the other hand, GIS develop-ers can find and use one or more availableGIS Web Services to use as building blocksfor creating integrated GIS applicationsbased on user requirements. By integrat-ing various GIS Web services from differ-ent GIS servers and using them as build-ing blocks, GIS applications would becapable of access to user resources as wellas different GIS server resources.

In all paces of these interactions, XMLplays a major role. It can be used efficient-ly to exchange spatial data and invokingvarious GIS methods remotely throughSOAP. In addition according to Amirianand Mansurian (2006), other XML tech-nologies can be used to improve the qual-ity of GIS Web services:

• Using different namespaces and XMLschemas to support diverse object models,

• Applying XSL and related technologiesfor mapping different object models andalso graphical rendering of spatial data,

• Utilizing different technologies such asVML , SVG and X3D for 2D or 3D visu-alization of spatial data

As described in the previous section,Web services technologies provide theability to separate semantic and func-tionality of a service. As a result GIS Webservices would be implemented by usingany software platform, middleware sys-tem, programming language, thus het-erogeneous GIS Web services can be inte-grated seamlessly and dynamically.

All in all, Web services Technologies arethe main candidate for GIS application

integration and resolve the technicalnon-interoperability problem associatedwith current GIS software.

CONCLUSIONSince Web services are the foundation ofnew type of interaction- interoperableand open application to application com-munication- they provide an unprece-dented opportunity to overcome thetechnical non-interoperability problem inGIS world.

Meanwhile, there are lots of issues dueto immature nature of Web services to beresolved. In addition, considering thenature of spatial data and GIS, some morespecific issues are faced by GIS Web serv-ices such as authentication and authori-zation of GIS Web service users, high vol-ume of spatial data, methods of compres-sion and supporting the complicated GISworkflows that should be dealt with.

Finally design and development of adistributed GIS service based on serviceoriented architecture and Web servicesplatform is ongoing.

Land and its resources have been thebasis of wealth. Humankind has gen-

erated much interest over several years todevelop suitable forms and rational methodsof administrating and managing land.

A multitude of emerging technologies has been created toenhance describing and valuating all land related resources. Thegeographical information systems denoted GIS aided to modernmanagement approaches contribute in setting up a core strate-gy that meets decision maker as well as user requirements. Thecurrent paper addresses the impact of implementing GIS appli-cations serving the society and leading to a homogeneous LandInformation System. It also discusses many challenges facingtheir use and their role in ensuring many potential benefits.

telecommunication networks. In thescope of GIS, Internet is a powerful meansfacilitating the access, processing, anddissemination of geographical informa-tion and geographic knowledge. Theprogress of information technology hasdramatically influenced the developmentof GIS technology. A series of faster com-puters and storing devices are continu-ously appearing and changing the waywe deal with our complex problems. Therecent development of wired and wire-less data communication has made possi-ble GIS technologies to evolve from main-frame and stand alone desktop GIS to dis-tributed GIS [5]. Presently, users canaccess and operate GIS applications fromany location supporting web browsers.While the mainframe and stand alonedesktop GIS are centralized systemsbased on platforms incorporating soft-ware packages and data, Distributed GISare developed around an advanced net-working technology, which can enableconnecting a series of different systemsand platforms. Distributed GIS refers toGIS programmes running on the Internetcalled Internet GIS or on wireless net-working technologies called Mobile GIS.Recently, many organizations are experi-encing more distributed services throughgeographically dispersed networks andweb-based GIS to meet their specificrequirements. Then, Internet GIS is thebasic tool that permits developing anEnterprise GIS, which focuses on buildinga comprehensive infrastructure enablingto make a best way to take benefits ofmultiple companies' resources [4].

IMPACT OF GIS AND INTER-NET GIS ON DELIVERY OFKEY LAND ADMINISTRATION

Information Technology and geo-graphic knowledgeThe World Bank's 1998 report on worlddevelopment stated:" knowledge hasbecome perhaps the most important fac-

tor determining the standard of living ……Today's most technologically advancedeconomies are truly knowledge based".Knowledge is generally built upon infor-mation extracted from data and has thecharacteristics to add values to this infor-mation. Geographic information as a spe-cific information is obviously leading tobuild a knowledge dealing with spatialphenomena. The GIS technology has theability to gather general and specificinformation about the real world and todeliver useful solutions for society prob-lems. GIS involves various kinds ofknowledge based on scientific rules,sophisticated materials, and specific val-ues of land information to present appro-priate solutions with respect to severalobjectives. This permits to decision mak-ers to conceive new approaches of gov-erning effectively land resources regard-ing the existing legislature and laws.New services are developed and newinformation and business activities arefacilitated and improved.

GIS and Land Information Systems The GIS has been positively influenced bythe information technology progress andthe geographic knowledge development.Several GIS applications have been devel-oped dealing with many different data toenable spatial searching, overlay opera-tions, spatial analysis and modeling. Akind of GIS based applications is LandInformation Systems, which indicateevery system producing spatially refer-enced information on land referring toproperties and natural resources. LIS arecombining human and technicalresources, with a set of organizing proce-dures, to provide information in supportof management activities [1]. They areconcerned with detailed informationrecorded at the local level so they may bemapped at large scales. They serve thedecision-maker to develop and to up-grade the national trends for land man-agement. They have the benefits to serve

society on a long-term basis and on along-term return on investment. Theirultimate objective is to become a key ofland administration by considering bothstatic and dynamic aspects of land [2].Land administration has in its down-stream reliable mapping infrastructures,which come from cadastre and surveymapping, and in its upstream good man-agement, which is an operational processof implementing land policies in compre-hensive and sustainable ways [3].

Social and economical impacts ofInternet GIS technologiesWhile GIS technologies have the aim toenhance processing, analysis, and diffu-sion of geographic information, InternetGIS focuses on sharing geographic knowl-edge built up of a potential networkingtelecommunications.

The Internet GIS solution creates aninter-departmental cooperation and aninter-local coordination and ensures aninteroperable land information system.The availability of distributed land infor-mation permits to treat additional formsof social and cultural information. Themore relevant information we process fora particular environment, the more relia-bility and social confidence we obtain.The reliable land administration data willimprove land management, land owner-ship administration, land resourcesassessment, network infrastructure stud-ies, and transportation activities.

er, it is required to introduce the technol-ogy across different levels.

CHALLENGES OF GIS AND INTERNET

Capacity buildingRecently, the GIS technology evolves rap-idly to encompass different domains ofthe real world from the simplest applica-tions to manage a series of data for deter-mining some statistic results, to the hugeand complex systems serving to analyzeand make decisions. Critical efforts havebeen made to support and improve GISengineering goals and principles in termsof suitability, accessibility, reusability,and reliability of the adopted pragmaticsolutions.

Many researchers have discussed vari-ous solutions and concluded that to everyproblem are associated specific GIS solu-tions. Crucial works should be done tofurnish a suitable framework enabling todevelop land administration based GISand Internet GIS technologies. Thisframework incorporates various institu-tions dealing with positioning tech-niques such as geography, cartography,and geodesy, and development methodssuch as data modeling, design tech-niques, and software programming.Another challenge is the familiarizationwith the new solution, which encom-passes the development of a scheduleplan for advanced staff training in theweb, Internet knowledge, and network-ing security. Countries, especially devel-oping ones, face difficulties in developingskills and competences of the involvedstaff in land administration.

Institutional barriers The institutional barriers mean the issuesthat refer to organizations involved in alarge distributed Internet GIS solutionand the legal aspects that regulate andcarry out land administration. The insti-tutional arrangements concerning laws

and regulations should be handled andenhanced to provide a proof of success inmanaging land in an integrated system.The development of Internet GIS solutioninvolves many organizational entities;regions, municipalities, public agencies,private companies, academic institu-tions, and commercial groups. Theunique denominator of these organiza-tions is their common interests in landinformation.

They can share costs, motivate enoughpeople, and generate enough resources tosuccessfully implement land administra-tion system. Another important barriercomes up; it is the internal considerationof each organization. The members of cer-tain organizations can have a lack offamiliarity with new concepts of themodern technology.

In other organizations, we can find alack of training and management sup-ports. To overcome these barriers, severaltechnical supports during should be pro-vided such as:

• Furnishing comprehensive geographicknowledge and clear ideas about landadministration paradigm,

• Providing training session of involvedstaff from organizations that contribute tothe implementation,

• Removing smoothly the traditional prac-tices in handling lands to introduce theGIS/LIS and Internet GIS technology,

• Proposing a motivating system toenhance the statutory conditions of theinvolved staff.

CONCLUSIONIt is inevitable that the integration of GISand Internet GIS technologies in our soci-ety will require new and expensive oper-ational tasks. The institutional commit-ment and involvement around a newsystem needs more time to be opera-tional. The development as well as theenhancement of the staff skills requiresmore financial supports to promote theintroduction of the new technology. Con-sidering these requirements, it is indis-pensable to focus on a successful

approach to deal with the multiple tasksof the land administration. First, weshould conceive incremental phasesinstead of creating the whole solution.Second, it is necessary to encourage theprinciple of data sharing among all con-tributors to ensure the potential benefitsof land information.

Third, the standards and guidelines forthe use and sharing of land data shouldbe developed. Fourth, it is recommendedto define a reference of quality control toimprove the positional accuracy, theattribute accuracy, and the dataexchange and production quality. Fifth,an appropriate scheme of automationshould be designed by choosing betweencentralized or distributed configurations.

planning the conservation and managementof the natural resources and the develop-ment of ecotourism activities on the island.

The island has witnessed high rates of change in land use inthe past few years; environmental management approacheshave been implemented since the mid 1990s with a vision forimproving the decision making process and providing quick andaccurate services to researchers and the ecotourism communityin general. The building of an integrated spatial database, dur-ing the current phase, is an important step towards the achieve-ment of the actual research objectives. A spatial database con-taining 15 GIS layers was built; both raster and vector layerswere integrated; the data is projected in the UTM zone 40N. Theoutcome of the change detection analysis task, conducted dur-ing the first phase of the project, was also added to the database.The integration of multi-scale aerial photographs in a GIS data-base is of great importance and has a high cost to benefit ratio.

The objectives of the present study are summarized below:

• Evaluation of the change rates and extent during study period;

• Creation of GIS layers related to the environment of the island;

• Building a spatial GIS database for optimal land resource man-agement of the island.

BACKGROUNDThe creation of a spatial GIS database is a major objective of theactual study. To emphasize the issues related to the manage-ment of the island resources, multi date large scale aerial photo-graphs were scanned, georectified and integrated into the spa-tial database. Six different dates were considered, the only avail-able data!, mid-1970s, mid-1980s, 1999, 2000 and 2005 aerialphotographs with spatial resolution 1 to 2 meters. Vector datawere derived from the 1999 and 2005 by on-screen digitizationto evaluate the change occurred on the island during this activeperiod of management and laying down of infrastructures onthe island.

A total of 11 different GIS layers were produced namely: roads,roundabouts, footpaths/tracks, buildings, breaks/bays/ports/petrol station, palm trees, mangroves, shrubs, water bodies,water channels, and barren land. A DEM will be generated andadded to the database on a later stage because cuts, filling, andthe creation of new artificial hills continue to be done duringour study.

The basic principle in using remotelysensed data for change detection is that:changes in the objects of interest willresult in changes in reflectance values orlocal textures that are separable fromchanges caused by other factors such asdifferences in atmospheric conditions,illumination and viewing angles, and soilmoistures.

STUDY AREAAL Sammalyah is located at approximate-ly 24o 26'10"N - 24o 28'56?N and 54o29'22?E - 54o 34'12?E (figure1). Situated inthe Arabian Gulf, about 12 km north eastof Abu Dhabi Island near (Um al-NarIsland) area and just opposite Shati'-AlRaha beach, is characterized by its richecosystems and marine life. The Islandarea covers about 14 square kilometers.Soil texture is dominated by sand, withhigh salt content reaching 31.5% TSS onthe surface, being mostly Chloride solu-ble salts giving a white colour to the soilsof the island, which produces high bright-ness levels on satellite imagery operatingin the visible portion of the EMR, howeverthe very narrow mangrove soils sur-rounding the island have dark colorbecause of high content of organic carboncontent. The Island is a natural reservecontaining high biodiversity, mangroves(Avicenna marina), including: Arthrocne-mum macrostachyum, Seidlitzia rosmari-nus, Suaeda vermiculata, and Cyperusconglomerates.

A change detection analysis using mul-ti-sensor and multi-temporal aerial pho-tographs and satellite imagery can helpin emphasizing changes in LandUse/Land Cover (LULC) that has occurredsince the establishment of the DER in1996, and to assess the degree of successin the implementation of the DER's man-date in protecting and developing theecosystems of the island.

DATAA temporal series of remote sensing data

was acquired forthe study area. Itwas composed ofaerial photographsfrom mid-1970s,mid-1980s, 1999,2000, 2005, and2006. For conduct-ing the changedetection study,aerial photographsfrom 1999 and2005 were used;this is becausechanges were visi-ble on availableaerial photographs only from the 1990s.No major activities were noticed from themid-1980s aerial photographs.

The software used includes ESRIARCGIS9 software for vector processing,and ERDAS Imagine 8.4 for image pro-cessing. The selection of data, used in thisstudy was largely governed by availabili-ty and accessibility of archived data especially at the MSD archives; the selec-tion of hardware, and software was gov-erned by the UAEU geology department'sfacilities.

METHODOLOGYThe methodology applied to the changedetection analysis in this study is basedon integrating GIS with remote sensingmethod, including the advantage ofusing GIS ability to incorporate differentsource data into change detection appli-cations. Available high resolution aerialphotographs of 1999 and 2005 were used,and a post-classification comparisonmethod is implemented. Visual analysismethod was used for image interpreta-tion and simultaneously an on-screendigitizing of changed areas was per-formed. Texture, shape, size and patternsof the images were used for identificationof LULC change through visual interpre-tation. A unified land cover classificationscheme was established for classification

of images. Eleven land cover classes wereidentified in the image interpretationprocess (Table 1). The classified imageswere then used to derive class area statis-tics and class patterns over the past 6years. The output layers are brought intoa GIS database.

The methodology applied to the GISdatabase building follows the followinggeneral steps:

• data sources selected for entities andattributes are available large scale aerialphotographs used in the change detec-tion analysis (1999 and 2005), in additionto 11 vector derived layers. Other rasterdata include aerial photographs and hiresolution satellite images covering theisland. DEM is generated from availablespot heights. Other land cover types willbe digitized and added to the database frothe 2006 aerial photograph later.

• ArcGIS version9 geodatabase structureis adopted for the design and building ofthe database

• shapefiles created by digitizing usingArcGIS 9 under Edit session, then con-verted to the database using geoprocess-ing tools available in ArcGIS.

RESULTS Production of a set of imagery spanningthe period from the mid-1970s to the verynew 2006 aerial photo. Imageries aregeometrically corrected, co-registered,resampled to a pixel resolution of 2meters and projected to the UTM projec-tion zone 40N. Eleven land cover classes

were produced and converted to vectorformat for the 1999 and 2005.

Two land cover maps were produced for1999 and 2005. Eleven land cover classeswere mapped and categorized into fourgroups, these include:

• Category 1 (Urbanization): Roads,Roundabout, and Buildings; as indicatorsof urbanization

• Category 2 (Forestation, Environmentaldevelopment): Mangrove (near the NNEcoast and in the inner parts of the island),Palm trees (along roads and as firm bor-ders) and other trees and grasses (nearthe ENE coast); as indicators of foresta-tion, agricultural activities, and environ-mental development.

• Category 3 (Desertification and land dis-turbance): Barren land, Tracks and Foot-paths; as indicators of desertification andland disturbance.

• Category 4 (Conservation and landreclamation): Water bodies and waterChannels; as indicators of conservationand land reclamation.

Figures 2 and 3 show some examples ofthe database layers produced during thestudy, while the aerial extent of the covertypes for the years 1999 and 2005 are pre-sented in table 2.

DISCUSSION

Change Detection AnalysisUrbanization: changes in roads, round-abouts, and building (1999 - 2005)

Table 2 shows that there has been anincrease of 23.6%, 300% and 220% inroads length, number of roundabouts andbuildings areas respectively between

1999 and 2005. This high increase of thelevel of urbanization in the islandrequired large amounts of investmentfrom the managing organization knownas the Emirates Heritage Club, to satisfythe increased demand to build newtouristic, scientific and sports facilities;e.g. horse riding halls, Olympic shootingrange, Olympic swimming pools, labora-tories, green houses, offices, dormitories,and the establishment of a modern roadnetwork.

These facilities are used to host increas-ing numbers of students from all aroundthe country as well as researchers and toemphasize ecotourism. This is attributedto the high-level political will of H.HSheikh Sultan Bin Zayed, Chairman of theEmirates Heritage Club to transform theisland from a desertified area into a well-developed reserve for protecting wild lifeand ecosystems and for developing eco-tourism and preserving local heritage.

Forestation, agricultural activities andenvironmental development: changes invegetation cover extent (1999 - 2005)

Total vegetation cover extent hasincreased from 3.742 km2 in 1999 to 5.101km2 in 2005, an increase of 36.3%between 1999 and 2005. The density ofthe vegetation has also increased givingincrease to the overall biomass produc-tion on the island. This biomass produc-tion can be quantified using vegetationindices calculated from satellite imageryand will eventually, be one of the objec-tives of future studies using satellite

imagery. Furthermore, this increase invegetation extent is mostly attributed tothe increase in mangrove planted areas;indeed mangrove planted area hasincreased from 2.256 km2 in 1999 to 3.568km2 in 2005, an increase of 58.2% in aboutsix years. This gain in the mangrove -occupied areas has occurred on previous-ly barren land which has been reclaimedand irrigated using sea water hence indi-cating the success of procedures appliedto combat desertification, enhance biodi-versity and sustain the environment onisland. Mangrove is highly adapted to theconditions of the island and is known forits high salt-tolerance, as a soil stabilizer,an ideal marine and bird habitat, and cansustain bees' elevation giving uniquenessto mangrove honey production.

This success in the extent of vegetatedareas especially mangrove plantations,gives evidences that the UAE is wiselyinvesting in the domain of scientificresearch oriented at producing speciesthat are adapted to its climatic conditionsand hence increasing green areas andcombating desertification locally and inthe region.

Deesertification and land disturbance:changes in barren land extent and foot-path lengths (1999 - 2005)

Barren land extent was studied as anindicator of desertification and abun-dance of green vegetation throughoutthe island, while tracks and footpathslengths are used as an indicator of landdisturbance and hence another indicatorof desertification. There has been adecrease of 15 % in barren land areasbetween the two dates; while tracks andfootpaths lengths have decreased by 32%between 1999 and 2005. This is anotherindicator of the decrease in desertifica-tion levels and the development of theecosystems on the island during studyperiod. The loss in the bare and disturbedareas is due primarily to new vegetatedareas (85%), urbanization (11%), and waterbodies and water channels (4%).

Conservation and land reclamation:changes in water bodies and water chan-nels (1999 - 2005)

The spreading of water bodies andwater channels is clear evidence of con-servation and land reclamation. Table 2shows that there has been an increase of13.7% in the channel networks betweenthe two data sets while water surfacesappear on the 2005 imagery only, with alarge artificial salt water lagoon of 15,000m2 (figure 4).

Water surfaces are designed to attractmigrant birds during the winter seasonand to develop aquatic life on the island,while channels are used to bring high-tide sea current generated water intomangrove areas.

Database buildingAl Sammalyah GIS database contain bothraster and vector data, large scale aerialphotographs were scanned and convert-ed to ArcGIS geodatabase format. Vectordata were obtained from on-screen digiti-

zation of the 1999 and 2005 datasets, andare added to the geodatabase. An inte-grated geodatabase of six different datesof large scale aerial photographs, 11 vectorlayers spanning 3 different dates wereobtained totalizing 33 vector layers show-ing the status of the land cover on theisland during 1999 and 2005 dates, andassessing the rate and nature of changeoccurring on the island.

Results indicate good progress in thelevels of greening of the island, especiallyin the increase of the salt-tolerant man-grove plantation during the study period.A geodatabase of about 40 GIS layers isnow available to the decision makers ofthe island for the best management of itsland resources.

CONCLUSIONOn the island large-scale reclamationstarted in the early 1990s and hasincreased very rapidly since then. This isconfirmed by the decrease in bare landand the increase in vegetated areas espe-

cially plantations of salt-tolerant man-groves and palm trees. Urbanization andthe spread of water bodies is testimony tothe development of the island forenhancing scientific research and devel-oping the ecosystem.

Oil spill spreading fast

G I S D E V E L O P M E N T - M I D D L E E A S T

Through the World attention isfocused on the fight and resulting

human casualties out of armed conflictbetween Israel and Hezbollah, the environ-mental damage caused in the region alsoappears severe. Many of the once-pristinebeaches in Lebanon are black with oil. Abombed power plant about 30 kilometerssouth of Beirut and within 100 meters of thesea burnt for over three weeks. It pollutedthe skies with black smoke and leaked thou-sands of barrels of oil into the sea. Environ-mentalist Wael Hmaidan says, "If there was-n't other issues covering this problem thiswould be the story of the year in theMediterranean region."

Satellite imagery shows rapid spreading ofthe oil slick. More than 80 kilometers ofcoastline have been affected. There arereports of problems all the way to Syria. BerjHatjian is with Lebanon's environmentalministry. "What we have here is the equiva-lent of a tanker sinking into the sea and 20to 30,000 tons reaching the shore line."

Edgar Cherab is with the United NationsEnvironmental Program. He worries aboutwhat can be done. "We don't have the equip-ment nor the proper knowledge in the coun-try." Fishermen and marine life are feelingthe first effects of the spreading oil. Esti-mates differ wildly on the amount of oilspilled and the extent of the destruction.United Nations' experts coordinating dam-age and clean-up efforts say any oil slick ofthis magnitude will have serious ramifica-tions for the environment.
