Working Committee Real Estate Cadastre (AK LK)

The AK LK has the task of maintaining the uniformity of the official geometric and factual data (geospational reference data) for the model, application-neutral description of the properties on the earth's surface. For this purpose, standards for the collection and homogeneous management of the geospational reference data of the real estate cadastre as well as for the provision of products are coordinated and recommended for use.
