Spatial data is geographic data that storesthe geometric location of particular features, along with attribute information describing whatthese features represent. Spatial data is also known as digital map or digital cartographic data.5.1.5 Image dataImage data includes satellite images, Air photographs and other remotely sensed or scanned data.5.1.6 Tabular dataTabular data includes almost any data set, whether or not it contains geographic data. Someviews are displayed are displayed directly on a view directly; others provide additional attributesthat can be joined to existing spatial data. ArcView supports the following formats: i) Data fromdatabase servers such as Oracle, Ingres, Sybase, Informix, etc. ii) dBase III files iii) INFO tablesv) Text files with fields separated by tabs or commas. XY event tables are used in this project.5.1.7. Extensions of GISSome extensions of GIS used in the project re as follows:i) 3D Analyst3D Analyst is an extension that adds support for 3D shapes, surface modeling, and real timeperspective viewing to ArcView. Spatial data can be created and visualized with 3D analystby using a third dimension to provide insight, reveal trends, and solve problems.ii)GeoprocessingThe Geoprocessing is an extension which performs spatial analysis function in ArcView.
