Maps are abstraction of reality.
Map features are represented symbolically at a reduced scale and identified by name and type. Map projections represent all or part of the surface of a sphere onto a flat plane with some distortion in shape or size. Map features are grouped by feature types or layers. Place, proximity to, connectivity, adjacency and other spatial characteristics are important to land related decision making and information use. Positions of features on the ground are described in relative or absolute terms.
