Cadastral map

Cadastral maps are used to accurately list the boundaries of countries,counties, or even just local land parcels. They are used to accurately record metes-and-bounds. By using GPS coordinates cadastral maps are able to show the precise location of a particular piece of land and its exact dimensions. This particular cadastral map shows parcels of land in St.Louis circa 1870.
