Property Base Map Law and Legal Definition

A base map with respect to property means a map with reference points on which land ownership data can be plotted. Reference points include state, county, township, or state and geodetic coordinate lines, or other features. It is also possible to outline additional geographical or topographical data on a base map.

The following is an example of a case law on base map:

A property base map submitted in a court of law must meet the requirements with respect to sheet size, scale, property acreage calculations, delineation of courses and distances of property boundaries, dedicated street rights-of-way, and easements.
