The Address-BDR-Online is the common recording pathway for data transmission to the Buildings and Dwellings Register and to the Address Register. Data can be entered either via a web application or via web services.
A description of the ABDR can be found in the document Overview (available in German language only).
The address register contains spatial address data down to building level.
In addition to addresses of parcels, buildings and units of use, the Buildings and Dwellings Register also contains structural data on buildings, dwellings and other units of use, as well as data on construction measures.
