ALKIS – Basic data stock/Inventory data extract Land Bremen

In the Official Property Register Information System (ALKIS®), all data of the real estate cadastre are merged. It contains the data of the formerly separate Automated Property Map (ALK), the Automated Property Book (ALB) and the Border Proof.
ALKIS® includes a federal, object-based data model by systematically linking the spatial (map) and non-space-related (book) data and maintaining them without redundancy. Data storage is carried out with metadata and history management.

The user has a federally defined ALKIS basic database at the disposal of the user.
These include: Parcels/location/points, Actual use, Buildings, Constructions/Facilities/Other facilities, Owners, Legislation/Treasury Units/Catalogues, Relief, User Profiles, Migration.

The data is provided via the uniform standard-based exchange interface (NAS) in a user-related inventory data update procedure (NBA procedure).
