Land registration Land is recorded in a two tiered system Registration of land parcels / real estate cadastre land register l The real estate cadastre has the task to describe the facts of the individual parcels of land (real estate), l while the land register (Grundbuch: register of title) provides information on the legal aspects (status of ownership etc. ) SAPOS, Germany European CGSIC Meeting December 5 and 6, 2002 7

The real estate map contains primarily the graphic representation of l l l individual parcels of land their boundaries buildings topographic features results of land valuation nature of land use and boundaries SAPOS, Germany European CGSIC Meeting December 5 and 6, 2002 8
