ALKIS

ALKIS stands for Amtliches Liegenschaftkatasterinformationssystem, which translates to Official Real Estate Cadastre Information System. It is a German nationwide system for managing and providing digital real estate cadastral data. ALKIS serves as the central repository for information about land parcels, buildings, and other real estate features.

The primary goal of ALKIS is to ensure the consistency and availability of high-quality cadastral data across Germany. It consolidates information from the former Liegenschaftskataster (real estate cadastre) and the Topographische Kartographie (topographical mapping) into a unified data model. This integration allows for a more comprehensive and accurate representation of the real estate landscape.

ALKIS data includes geometric information, such as boundaries and coordinates of parcels, as well as attribute data, like ownership, land use, and building details. This information is crucial for various applications, including land registration, urban planning, environmental management, and statistical purposes.

The system is maintained by the respective cadastral authorities in each German federal state. They are responsible for updating and providing access to the ALKIS data. Different types of users, ranging from government agencies to private companies and citizens, can access ALKIS data, often through specialized software or online portals, depending on the permissions and agreements in place. The standardization of data and processes through ALKIS contributes to the efficiency and reliability of real estate information management in Germany.
