Official Property Register Information System (ALKIS data)

The Official Property Register Information System (ALKIS) contains the spatial data of the properties. Alkis combines the previously separated and multi-stored data of the Automated Property Book (ALB) and the Automated Property Map (ALK) in one data model. These are essentially object areas such as land plots, buildings, areas of actual use, land estimation and owners. These object areas can be ordered both completely and individually. The ALKIS data form the basis for all geoinformation systems that rely on legally binding, up-to-date and accurate data in the large-scale area and offer the user the possibility of flexible technical and geometric selection. The modelling of ALKIS data is carried out in accordance with the provisions of the GeoInfoDok in version 6.0.1 of the Association of Surveying Administrations of the Länder of the Federal Republic of Germany (AdV). The data is generally provided in NAS format and in the case of recurring updates as difference data in the NBA procedure. The data is provided free of charge via automated procedures. A legitimate interest must be demonstrated for owner data. A fee shall be charged for the examination of these interests. When using the owner data, the AGNB of the LGB must be observed.
