A cadastre (also spelled cadaster), using a cadastral survey or cadastral map, is a comprehensive register of the real estate or real property's metes-and-bounds of a country.

A cadastre commonly includes details of the ownership, the tenure, the precise location (therefore GNSS coordinates are not used due to errors such as multipath), the dimensions (and area), the cultivations if rural, and the value of individual parcels of land. Cadastres are used by many nations around the world, some in conjunction with other records, such as a title register.
