Avoiding the need for multiple feature types (points, lines and polygons) Supporting rapid computations and multi-variate data.ДЎ1 Express coordinates in decimal degrees. Work well for Representing continuous data. Smaller cells result in a more detailed map, but also greater disk storage requirements. Reduced disk storage space requirements Surface of map is divided into a gridwork of square cells, each of which is assigned a data value reflecting the characteristics of that particular square. areas or regions) Work well for Accurately representing the size and shape of entities such as buildings, political jurisdictions, real estate boundaries, roads, etc. Raster Data Vectors Rasters Can take the form of Points Retrieved August 31, 2015, fromД© Vector vs. states.Дata mapped using GIS takes one of two basic forms: Vectors Rasters The Nature of Geographic Information. Try to minimize distortion in Shape, Area, Distance or Direction (SADD) Examples: State plane projections used to represent various U.S. typically tailored to a particular purpose or geographic area.
