The history of today's cadastre begins in 1817, when the measurement of the Austro-Hungarian Empire was decreed by law, to provide the stipulation of property tax on an equitable basis.
The cadastre is next to the Land Registry, the second pillar of the Austrian system of property land securing. In the digital cadastral map (DKM), whose creation began in 1989, existing plans of the very first cadastre, the new cadastre and the previously valid cadastral map are incorporated. The DKM is only illustrative of the mutual position of the ground areas. The land register lists owners, rights and easements.
The actuality of the cadastral map basically depends on the affected landowners and the relevant planning authorities.
