The Key register Kadaster (Basisregistratie Kadaster, BRK) consists of the cadastral registration and the cadastral map (Kadastrale Kaart). The cadastral data are used by many clients as the foundation for their own work processes. In that sense, the Kadaster has been a key register for a long time. The Kadaster’s products remain available through MijnKadaster and the other channels. Direct links to other key registers will enable incorporation of the data of other registers into the cadastral register and products.
