WhatisGIS?GeographicInformationSystem

Part1:IntroductiontoGIS

Definition: A geographic information system (GIS) integrates hardware, software, and data to capture, store, analyze,manage,anddisplayvariousformsofgeographicallyreferencedinformation. Todays GIS involves collaboration of various technologies and disciplines like geography, cartography, surveying, remote sensing, satellite imagery, photogrammetry, spatial statistics, mathematics, geometry, topology, computer science, information science, library science, web technology,etc. WhyGIS? GIS integratesvarietyofdatawithaspatialcomponentregardlessofitssource, storesandmanagesthedata, analyzesthedataasawholeanddisplayitinvariousformats, leveragesvisualizationtomakecriticalbusinessandplanningdecisions,andhenceitsaves tremendoustimeandmoney. Example:

Point(landmark,tree,etc.) Line(street,river,stream,etc.)

Polygon(landparcels,buildings,etc.) Topography(terrain,contours,etc.) RasterImage(satelliteimagery,historicphotos,etc.) Integratedrepresentationandmanagementofdata

Applications: ThereareseveralapplicationsofGIStechnology.Itcanbeusedforurbanplanning,historicmapping, archeology,environmentalstudies,transportationstudies,emergencymanagement,healthstudies,

ecologicalstudies,assetmanagement,naturalresourcemanagement,marketing,economicstudies, demographicstudies,crimestatsmapping,affordablehousinganalyses,andmanyotherpurposes. Forexample: GIScanbeusedtomapasthmaratesofspecificneighborhoodinthecityanditssurroundingland use patterns. GIS can be useful to simulate disaster planning and to map evacuation routes and fastestroutesforambulancestoreachtotheemergencysites.GIScanbeusedtodeterminethebest locationforasupermarkettolaunchitsbusiness. WhatisArcGISDesktop? ArcGISDesktopisaGISproductcreatedbyESRI(EnvironmentalSystemsResearchInstitute)thatallows you to analyze your data and author geographic knowledge to examine relationships, test predictions, andultimatelymakebetterdecisions. ItisafamilyofthreeproductsArcInfo,ArcEditor,andArcViewthatsharethesamecoreapplications, userinterface,anddevelopmentenvironment. ArcGISDesktop

EachproductprovidesadditionalGISfunctionalityasyoumovefromArcViewtoArcEditortoArcInfo. KeyFeaturesofArcView: - ArcViewallowsperformingbasicvisualization(mapauthoring),spatialquery,editinganddata integration,andbasicmodelingandanalysisofyourdata. Visualization: o Map authoring: e.g. predefined map templates to save time, easy to create a consistentstylemaps,etc. Spatialquery: o e.g.measuredistancesandareas,findfeaturesinthemap,selectdatabylocationor attribute,switchtheselection,accesslayerproperties,etc.

e.g.Proximityanalysistofindoutwhichclosestservices. Simplefeatureeditinganddataintegration: o e.g. create/edit point,line,andpolygonfeatures and attributes, integrate variety of data types including demographics, facilities, CAD drawings, imagery, web services, andmultimedia.

e.g.quicklymakechangestoseveralfeatures(records)atonce. Basicmodelingandanalysis: o e.g.modelspatialrelationships,generatecharts/reportsfromfindings,etc. ReadytoUseDatasets: o e.g. ESRI Data & Maps Media Kit, which is updated annually and preconfigured to workspecificallywithESRIsoftware. Enabledforextensions: o e.g.addevenmorecapabilitiesAnalysis,Productivity,andSolutionbasedextensions performextendedtaskssuchasrastergeoprocessingandthreedimensionalanalysis.
