Cartographic Representation

Center of Excellence for Geospatial Information Science (CEGIS)

Cartographic representation is how we display information on a map.

Topographic features that exist on earth’s surface—such as terrain contours, surface water features, roads, and buildings—are displayed on topographic maps.

Features are drawn with the amount of detail that can be clearly displayed within the map extent. Various cartographic generalization operations are required for this task.
