Official Property Cadastral Information System (ALKIS data)

The Official Property Cadastral Information System (ALKIS) contains the basic geodata of the properties. These are essentially property areas such as parcels of land, buildings, areas of actual use, areas of land estimation and owners. These object areas can be ordered both completely and individually. The ALKIS data form the basis for all spatial information systems that rely on property-binding, up-to-date and accurate data on a large scale and offer the user the possibility of flexible technical and geometric selection. The modelling of the ALKIS data is carried out in accordance with the provisions of the GeoInfoDoc in version 7.1.2 of the Working Group of Surveying Administrations of the Länder of the Federal Republic of Germany (AdV). The data is provided free of charge via automated procedures or self-extraction. For owner data, a legitimate interest must be proven. A fee is charged for the examination of these interests. When using the owner data, the AGNB of the LGB must be observed.
