Definitions Edit

A base map is

[t]he map of the community that depicts cultural features (e.g., roads, railroad, bridges, dams, culverts), drainage features, and corporate limits.[1]
a spatially accurate map that shows the georeferenced location of geographic features. These features include roads and railroads, streams and lakes, boundaries, other geographic features, and related names and labels.[2]

Overview Edit

"Most base maps are created today using orthoimagery, which are aerial photographs processed to have the spatial accuracy of a map."[3]
