Data Type: Shapefile Feature Class
Shapefile: G:\GIS\Week 7\Census2K\SHPFiles\LatLon83\Counties.shp
Geometry Type: Polygon
Geographic Coordinate System: GCS_North_American_1983
Datum: D_North_American_1983
Prime Meridian: Greenwich
Angular Unit: Degree
Working with the shape files and Arc GIS showed me how intricate the making of maps is and how the information can be rearranged to appear a certain way. You can make the map appear as if a small percentage of each race of people is living in each county, or appear that there is a high percentage. The information is readily available to be manipulated while making a map. It gives you a lot of freedom with the aesthetic properties of the map. You can change the colors, the class intervals and so on.
