A cadastral map is a map defining land ownership. The land register cadastral map is further defined by the Act as a map showing all registered geospatial data relating to registered plots. The cadastral map consists of cadastral units, each of which represents a single registered plot of land.
Cadastre is a technical term for a set of records showing the extent, value and ownership (or other basis for use or occupancy) of land. Strictly speaking, a cadastre is a record of areas and values of land and of landholders that originally was compiled for purposes of taxation. In many countries there is, however, no longer any land tax and in practice the cadastre serves two other equally important purposes. It provides a ready means of precise description and identification of particular pieces of land and it acts as a continuous record of rights in land.
