ALKIS – Official Property Register Information System

The Official Property Register Information System (ALKIS) is a product of the Association of Surveying Administrations of the Länder of the Federal Republic of Germany (AdV). In ALKIS, the previously separately managed data of the Automated Property Book (ALB) and the Automated Property Map (ALK point file, ALK floor plan file) were migrated into an information system. ALKIS is now the official real estate register information system. The main building blocks of the ALKIS program system are the acquisition and qualification component (EQK), the data storage component (DHK) and the output and presentation component (APK).
