GIS SOFTWARE

Geographic Information System software is designed to retrieve, store, display, manage, and analyse all types of the geographical and spatial data. GIS software lets you produce maps and the other graphic displays of geographic information for analysis and the presentation. With these capabilities a GIS is a valuable tool to visualize spatial data or to build decision support systems for use in the multiple organizations. GIS stores data on the geographical features and their characteristics. The features are typically classified as lines, or areas, points, or as raster images. On a map city the data could be stored as points, road data could be stored as lines, and the boundaries could be stored as areas, while aerial photos or the scanned maps could be stored as raster images. GIS stores the information using the spatial indices that make it possible to identify the features located in any arbitrary region of a map.
