Cadastral Map Law and Legal Definition

A cadastral map refers to a map that shows the boundaries and ownership of land within specified area. Some cadastral maps show details including district names, unique identifying numbers for parcels, certificate of title numbers, positions of existing structures, section or lot numbers and their respective areas, adjoining and adjacent street names, selected boundary dimensions and references to prior maps.

Usually these maps are maintained by the government, and they are a matter of public record.
