Base Map Definition

 

A base map contains the boundaries on the map without any data representation. Boundaries can be areas (also called polygons), curves (which are lines or polylines), and points. Base maps can be used with other maps to show features such as roads, streams, city locations, boundaries that have no data associated with them, and so on. You can overlay base maps on other thematic maps by creating the base map on a separate MapViewer layer.
