CHAPTER TWO

2.0 REPORT ON THE CONVERSION OF ANALOGUE MAPS

(DELTA AND KATSINA STATES) TO DIGITAL FORM.

Aim o f the prqject:

This project is aimed at updating the Delta and katsina states b

maps and reproducing it in digital format

2.1 METHODOLOGY

2.1.1 MAP PREPARATION

Once the map of the project was obtained, it was prepared for

scanning. The control points were identified and marked appropriately

to enhance Geo-referencing. This can come in either with grided or

ungrided maps. The maps used for both project were grided maps.

2.1.2 MAP SCANNING

The map sheets were scanned in the line art mode which can also

be in grytone mode. The line art mode is very usefbl when contours or

linear themes are the main things to be converted. This is because the

mode supports the semi-automatic vectorization on the other hand, the

grytone is preferred when other types of themes are to be converted also

# the type to be adopted depends on the project. It should be mentioned

that the higher the dot per inch (DPI) value; the brighter the scanned

image and the more computer space used. This is where the power of the

computer being used comes to play.

There is much software that could be employed for geo-

referencing but the one adopted for these projects was Autodesk

CADoverlay on the AutoCAD platform. The process involved in geo-

referencing using these software, are as follows,

i. Inserting the image such that the software recognizes it.

ii. Plot the control points

iii. Identify the control points on the scanned image

iv. Geo-referencing.

2.1.3 GEO-REFERENCING

Geo-referencing is a process in which the scanned map is oriented

to take its real life position in the computer. Some literature refers to

this as REGISTRATION, especially when a digitizer is being used

for the conversion.

(Scanned image)

capital, other towns/villages on the map, the road network and

riverslwater bodies. To vectorise, the Polyline tool is employed for this

purpose. Before the commencement of the vectorisation, layers are

created for each theme to be captured. For example, assuming we are

interested in capturing states and roads, layers are created for them and

each class of theme is vectorised into the appropriate layer. To

commence vectorisation, click on the Polyline tool, which is the fourth

on the Draw tools collection

B

To create layers, click on the Layers tool or type Layer on the

command line, followed by enter to have the drawing below:

Overwrite the Layer1 to a desired name, followed by OK. If you want

to vectorise on the layer immediately, click on the current button before

clicking on OK. Continue to change layers and capturing your data until

all themes of interest are captured.

The area covered by each of the local Government wets ensured to

form a close polygon in AutoCAD, so that it could be independent in

the Arc view sofkware for the vector data (point) the state caphl,

local government headquarters and the villages were captured using

point symbols because points on the hardcopy represent them. They

do not cover significant area on the map due to the scaie of the map

(1:500,000) for the linear data, the streamdrivers and the road

network were digitized to form a close polygon. These took week6 to

capture a11 the features on the map. The work was crosschecked,

necessary corrections were made.

2.1.5 IMPORTING FROM AUTOCAD TO ARC. VIEW, 3.20

The captured image was imported from AutoCAD to Arc view

3.2% the data base for the different features in the captured image

were created and populated.

Some errors were dictated in Arc view; corrections were made

using the hard copy of the state map in AutoCAD and imported back

to Arc view. At this point, I learnt that the essencefiportance of

converting analogue map to digital form is basically for the purpose

of updating an existing map, for easy manipulation of the map, as

well as for other purposes that is of user's interest

The survey result of the update was added to the map

having geo-referenced it.

I

2.1.6 PROBLEMS ENCOUNTERED

I t was a wonderful experience but only the difficulties I

personally faced in saving the work. Some of the work I did for. weeks

was not found on the system as a result of system crash.

2.1.7 CONCLUSION h

The maps were successfully converted to digital form for fhture

update. This single activity made it so clear to me that every map is

meant to be in digital format for easy manipulation to the users' interest.

CHAPTER TflREE

3.0 HEYOH'I' O N SKT'TING OCJ'1' SUHVEY DONE

3.1 AIM OF THE PROJECT

'I'he ailn of the project is to set out the plots of land as it's

contained in the plan.

3.2 'TITLE AND LOCATION O F SUHVEY

3.5.1 RECONNAISSANCE I

The reconnaissance was done by all the party members and it was

ascertained, where the controls are to be linked to, when carrying out the

survey.

3.5.2 SETTING -OUT, CUTTING AND PILLAHING

'I'he area was cleared using Bulldozers leaving few economic

trees because the developinent of the plots was to commence

immediately.

We were able to bury the rod on each of the point of the plots.

There were total of 240 plots we handled.

3.5.3 TRAVERSING

The theodolite was set on an existing control around the plot

area, the necessary temporary adjustments were done. The traverse was

run from the control to the plot beacons and back to the starting control,

it was a close loop and ail the recording was done in the field book.

3.5.4 HEDlJCTION COMPUTATION AND ADJUSTMENT OF

FIELD DA'I'A.

The field data were reduced and the coordinates compiled and

adjusted. All the computations were done with soflware called

GEOCA 1,

3.5.5 PHESENI'A'I'ION

The plan was plotted using AutoCAD 2000 and the necess&y

details added. The setting out was completely done

3.5.6 PROBLEMS ENCOUNTERED

Some of the economic trees left fell in the traverse line and we

had problem of inter-visibility between stations.

3.5.7 CONCLUSION

The setting out project was a huge success as this exposed me the

more and increased my interest in surveying and mapping.

4.4 ME'I'HO1)OIA)GY

4.4.1 OFFICE PLANNING WITH SATELLITE IMAGERY

The already Geo-referenced map of Abuja master plan and the

satellite imagery from which it is extracted froni was used to extract the

area of interest (Iki-Dei) in Autocad land development.

4.4.2 RECONNAISSANCE

ARer using the satellite imagery in the planning of the execution

of the job, we went to the area and observed some of the points chosen

to be used from the satellite imagery; we were also able to note the

boundaries and controls near the area of interest.

4.4.3 CONTROL EXECUTION

The selected points from the satellite imagery were noted during

the reconnaissance. We picked the coordinates of the points selected

using the total station. These coordinates were used to Geo -reference

the area extracted from the satellite imagery of parts of Abuja.

4.4.4 T O P 0 - SURVEY OF THE AREA

I t is essential and very important that the topographic survey is

carried out to enable the proper design of the layout. The

topographic survey was carried out by another term of surveyors. The

survey division in the O f k e of the Surveyor - General of the Federation

in corroboration with the Federal Capital Development Authority carried

out the topographic survey of the area.

4.4.5 DESIGN OF AREA IN PLOTS

'I'he design of the dei-dei layout was done by a GIS expert and

town planner in the town planning section Federal Capital Development

A uthority(FC1)A) using the Autodesk land development and Auto CAD

overlay software.

4.4.6 HACK CYOM Y UTATION J-M EZ b

The beacon points on the softcopy of the layout were noted using

a particular layer and colour to represent the beacons of the plots and

another layer and colour for the boundary lines.

The coordinates of the beacon points were copied in micro soft

excel since the image was geo-referenced, point in the layout gives the

coordinates of the very point in question.

'I'he extracted coordinates in micro-soft excel was imported into a

software (.I-MEZO muti-soft) automatic back computation to convert the

coordinates reading to bearing and distances automatically.

The gotten bearing and distances aided the location of the points

on ground as they are on the map.

4.4.7 SETTING-OIJT ON GROUND

'The coordinates extracted from the Geo-referenced satellite

imagery of the area in question were loaded in the flash card (IDS) of

17

the total station to Iw used in placing the actual ground position of the

plots beaco~~s.

The total station was set and leveled on a government beacon

around the area and orientation done with other known coordinates

within the area. 'l'hese were done in every point of hterest by calling up

the point identity as i t is stored in the flash card of the total station to

display on the screen of the total station the bearing to the point to be

located. The11 the distances were also recorded using the reflectors. , 4.4.8 IN-SII'U CHECK PRQMARK I11 GPS.

The base station was placed at a known control point. The rover

synchronized with the base station, the measured or computed

coordinates of all the control in the total station were transferred to the

CiPS in the ofice of the surveyor - General of the Federation. At the

field, the GI% rover receivers placed on the controls, the Geodetic GPS

only just required the beacon number as saved; the GPS measure the

coordinates of the control from the satellites. The GPS was allowed for

f 5 minutes for simulation and tracking of satellites after which it recalls

the keyed in coordinates by the identity and calculate to check the

difference (error).

(picking points)

The most of the controls picked by placing the GPS receivers on the

controls were the same while few of the controls had little errors but

within the limit of the allowable errors for the job.

4.4.9 CONCLUSION

The job was successfblly carried out. This particular job served as eye-

opener in surveying and mapping.

5.6 RECONNAISSANCE

We went for the reconnaissance of the land together with the said

owner. llc showed us round the boundary during which we saw some

existing beacons adjacent to the land which made the survey easier.

5.7 CUTTING AND PILLAKING

We were able to establish the position of the beacons and we

buried the rods marking the beacons and inscribing on them the pillar

numbers

to r instance

5.8 THAVEHSI NC;

'The total station was set on one of the known control beacons and

1 did the temporary adjustments. The traverse was run from the existing

(known co-ordinate) through the reflectors to the landed property and

hack to the starting point to form a closed loop.

5.9 OFFIC'E WORK

Download were made in which the data gotten from the field b

work were extracted and saved in the system. Software called J-MEZ

was used to carry out the adjustment.

6.3 DENSIFYING CONTROLS ALONG THE CENTER OF THE

'I'he detailing of the right of way of Enugu - Abakiliki road was

done by establishing points along the centre of the road. This is as a

rcsult of the specification for the federal high ways 300m interval of

controls along the centre of the road and along the sides 45m from the

centre of the road. b

'This was achieved using total station on 10 minutes static mode

and this was completed in one week. The base was set up on a primary

control and we would move the rover on the vehicle and the handheld

was set on 200m navigation mode. As the vehicle move, the distance

would reduce until it reads zero, then we would stop to set the rover on

the point to stay for 10 minutes and continued until the termination or

rather the limit of the job. The dimensions of the beacons were 40X

40X 1 Zcm width.

6.4 SETTING OUT OF RIGHT OF WAY AT BOTH SIDES OF

THE ROAD

This was done on Auto CAD land development sohare which

placed the points at both sides of the road at 45m from the centre of the

road. Downloads were done daily often a day work to free the

flash

card of the GPS for the next day job. The job lasted for two weeks and it

was a huge success.

6.5 CONCLUSION

The right of way demarcation was successfblly carried out

according to the specification given by the office of the surveyor-

General of the federation.

'I'hc client was able to show us the land. Reconnaissance was hter

carried out on a fresh day where we ascertained the control to link our

survey to.

7.6.1 SURVEY PROPER

The instrument promark 111 GPS with its reflectors were mounted

o n the existing Government beacon around the area. The control Was

transferred to the area in question. All the point indicated during the

reconnaissance was occupied using the stop and go method. This was a

bit cii fficult initially because of the poor satellite resection.

7.6.2 DATA PROCESSING

The survey data was downloaded from the flash card of the GPS

and we used GNSS global navigation satellite system software for the

post processing. The adjustment was done by hammering of the points

and the plotting was finally done in AUTOCAD 2004.

7.6.4 CONCLUSION

Even though we initially faced difficulty as a result of poor

satellite resection it was successfully carried out and quite an experience

for me.

8.4.1 PLANNING OPERATION

The planning for global positioning system is similar to

triangulation. A map of part of Nigeria was used for the planning.@A

wcll conditioned triangle was used for the baseline, the maximum of the

baseline must be determined. This is to minimize error in length for

hetter accuracy.

The time of the observation must also be put into consideration.

This can bc achieved with all" satellite availability" chart Almanac

installed on "leica GSP" ofice software. To access this Almanac, is

similar to star almanac, check satellite availability in leica GPS ofice

software by entering the data of observation. The available satellites

with respect to time of that day are displayed with the respective GDOP

(Geometric division of precision).

In the field: we navigated

to the point to be occupied using the handheld GPS since we couldn't

trace our own point. However, the reference was mounted on the L40

minna datum few hours before our team took off with our rovers to

respective stations to occupy. we were able to find the positions with the

hand held CiPS. Since the EIDC( expected position errors) was about 3m

radius on getting to the point the GPS beeped and that is a sign that .we

are within the point.

Ilowever, it was a static observation, the instrument was set up on

the station, and the tribra was mounted on the tripod, and properly

leveled on the station point

Consequently, since it is a differential GPS observation, we

started from the origin CL40( Minna datum) and coordinated other

points and extended the control to other points.

9.4 METHODOLOGY

9.4.1 ACQUISITION OF SATELLITE IMAGERY OF ABUJA

'The Quick bird satellite Imagery of Abuja was bought and was

prepared for the project. In the GlS lab in the office, image processing

was (image refinement enhancement etc) carried out using I L W

software. Then the image was exported to AUTOCAD 2000 where it

was properly gm-referenced with some coordinates of conspicuous

feature in the imagery which we did confirm with the hand held GPS.

These points were located and coordinated on the p u n d with the GPS.

9.4.2 VECTORISATION

All the feature in the imagery were vectorized using the AutoDesk

CAD overlay for automatic vectorization the vectorization took 6 days

to be completed.

9.4.3 IMPORTING FROM AUTOCAD TO ARC VIEW.

The digitized street guide of Abuja from the satellite imagery was

imported to Arc-view for population of data base. Some of the popular

places and roads were filled in and we (field men) were sent to the field

to get the street names and some important structures on the course of

getting the street names with the printed map of Abuja phase 1.

For each day we went to the field we come back to the office to

f i l l in the information on the system. This lasted for weeks and finally

we were able to cover the phase 1 of Abuja master plan.

9.4.4 POPULATION OF DATA BASE

All these data of streets, building names, roads etc were filled into

the AutoCAD and finally imported to arc-view for population. Different

layers were created for different features for proper quarry.

9.4.5 IMPORTANCE OF PROJECT b

It was realized that with such tool, one can achieve lots of things

with it. Among which are: - navigate phase 1 of Abuja master plan at a

glance. This street guide will be useful to:

Individuals and different cooperate bodies like Nigeria police, federal

road safety commission, fire services, to aid location of place and

shortest distance when the need arises in crime control, disaster

management, road network.

9.4.6 CONCLUSION

The project was successfully carried out and it was a niece

experience for me.

The training lasted for a week with a practical to demonstrate the

accuracy and our understanding of the principles of the instruments.

The training further exposed me practically on the use of GPS, in

carrying out survey jobs.

(Taking reading )

Downloads of the perimeter survey done to test the participants

understanding were downloaded and plotted using AutoCAD

The SR20 GPS and Promark I11 GSP receivers allow the user the

maximum flexibility, the GPS receiver can be used as a high accuracy

land surveying device, a powehl GIs data collector and reference

station also.

"transparency and cost of corruption" was attended.

10.1 CONFERENCES ATTENDED

I had the opportunity of attending conferences during my

industrial training.

The Annual General Meeting and conference (AGM) of surveyors

in Nigeria, held at Jos in crest Hotels, plateau state from 2"d-6th July,

2007 was attended. The different paper presentations extracted from

virtually every area in surveying at the AGM exposed me to the reality

in surveying. Theme is "Rural and Urban development in kigeria,

issues, problems and

The conference on survey coordination and advisory board on

survey training conference held at the international conference centre

area 11 Garki, Abuja from 1 0 ~ - 13 '~ September 2007, was

attended. The theme of the conference is "the role of surveying and

mapping in conflict management in Nigeria" the conference X-rays the

importance of surveying and mapping in conflict management.

about Global navigation satellite system (GNSS) GNSS is simply a

satellite communication technology that attends to the requirements of

Global navigation services, it is the standard generic term for satellite

navigation systems that provides a set of positioning, navigation and

timing services with global coverage.

CHAPTER ELEVEN

I I .O PROBLEMS ENCOUNTERED

The duration of the training was also marked by certain challenges,

though not enough to affect the smooth working condition during the

period. a friendly working environment was evident all through the

period of the industrial training . I gained GIs, surveying and mapping

knowledge respectively. therefore, 1 am ever grateful to SIWES for the I

opportunity 1 was offered that impacted and exposed me to my field of

study.

flowever. I experienced financial difficulty during the period of

my training; the cost of transportation was so high that the little I had

was not enough. that subjected me to work some distance on foot to get

to the office. I did not encounter serious problems

Also. searching for a place of attachment was a bit difficult,

checking the proximity of where one resides, It was quite a burden

moving from one place to another in search of place of attachment.

11.1 RELEVANCE OF THE SIWES PROGRAMME

The SlWES programme is a "must do" for all profession to expose and

further enlightened the student in one's area of specialization. I had the

privilege of working with modern surveying instruments like Leica

GPS, DNA10 digital level, Total Stations, Promark 3 GPS, etc in

carrying out surveying jobs. 42

I carried out the GIs processes severally. It was then that the

importance of digitizing maps became so real than it had ever been. I

also interacted with those at the helm of affairs when it codes to

surveying and mapping in the various Conferences/Workshops I

attended, that further boost my interest in Surveying as a profession.

I gained practical experience of AutoCAD, Arc View, Swfer 8,

Micro Station, GNSS, Google Earth Software and others. 1 had the

privilege of working with various States Administrative Maps. I dorked

with Delta, Bayelsa, Rivers, Katsina, FCT Administrative Maps.

With my present level of exposure, 1 now appreciate the value of

Surveying and Mapping in the development of the nation, especially in

the application of GIs in solving problems also the conversion of

analogue map to digital maps, for up date for the ever changing

environment of our country.

This experience is really going to have positive impact on my

career, and I thank SIWES once more and especially the Office of the

Surveyor-General of the Federation for the opportunity given to me to

get this high esteem of knowledge.

The SI WES period exposed me to civil service environment. It gave me the opportunity of having a fecl of the civil service environment, which is quite different from the academic setting. The entire experiences gave me an insight to what one will be exposed to after graduation. The SIWES period was quite interesting.

CHAPTER TWELVE r"

12.0 GENERAL, APPRAISAL OF THE PROGRAMME.

The SIWES programme could be improved on through the

following ways;

. 12.1 PROVISlON OF PLACE OF ATTACHMENT

There i s need for S I W S managerslorganizers to provide online

@ information concerning place of attachment that includes:

1. Names of establishment (that offer placement relating to one's

discipline)

2. The addresses of the establishments

3. The relevance of the establishment to different courses of study.

I discovered the need for such information to be in the SIWES website if

there is one and if there is none, they should get one to enable student!?

to access such on the internet. One of the ITF function is to provide

information on companies for attachment and assist in the industrial

placement of students.

12.2 REGULAR SUPERVISION OF STUDENTS.

It is the duty of the ITF to provide supervisions for students.

Unfortunately, all through my stay in the oEce of the Surveyor-General

of the Federation, no supervisor came. Regular supervision will enhance

the programme 44

for this will bring the consciousness to students and make them to be

punctual and participate actively in any task being undertaken by the

S establishments.

12.3 MONTHLY DISBURSEMENT OF ALLOWANCE.

Currently, the allowance payable to students by the Industrial

Training Fund (ITF) only gets to them at the end of the programme. It is

necessary to bring to the lime light the difficulties students go through

during the training period. Students' places of attachments are far fiom

home, they end up staying with relations, fiiends or get their

accommodation which is very demanding. In this case, students face

financial difficulties especially when the organization does not have any

financial provision for students on industrial training. With monthly

disbursement, students stand better chance of enjoying the programme

12.4 ADVICE FOR FUTURE PARTICIPANTS

Many students prior to their attachments consider monetary

commitments in establishment than the experience which is the aim of

SIWES, I therefore, advice future participants to put the experience fmt

for it is worth more than the money, money can come latter.

'This is the only opportunity to relate the theoretical knowledge in

the lecture rooms to practical work as experienced in the society and this '

must be taken seriously as this build and prepare one for a promising

Future

12.5 ADVICE FOR SIWES MANAGERS 1

To facilitate the full realization of the objectives of SIWES, it is

essential to ensure the proper training of students in preparing them for

world of work. One of the important instruments of maintaining this

programme is to get a website so that information can be accessed freely

concerning SIWES, Also, to ensure regular visit by the supervisor to

b places of attachment.
