Maps

• Entities such as customers, rivers, cities, states, and roads, that are displayed as points, lines, or areas on a map

Each layer is a group of map features. A geographic file can store either point, line, or area map features. The ccstatel file, for example, contains 57 area features: one for each of the 50 states, one for the District of Columbia, and one for each of the six U.S. territories.
