Difference data in the NBA procedure from the Official Property Register Information System (ALKIS-NBA)

The spatial data of the properties of the Official Property Register Information System (ALKIS) can be updated with the user-related inventory data update (NBA procedure). The NBA procedure in ALKIS replaces the BZSN or LBESAS procedures of the previous differential data methods for ALK or ALB data. For this type of ALKIS data provision, the user can determine, among other things, the updating rhythm, the spatial and content scope of the data delivery for his/her requirements. 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. 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.
