Official house coordinates Germany

The official house coordinates (HK-DE) define the exact spatial position of addressed buildings. The data source is the land register of the Länder and thus the official list of all parcels and buildings in Germany. Unlike data calculated by interpolation or otherwise collected, the nationwide available more than 22 million official house coordinates are based on an individual survey on site. They are continuously and comprehensively updated by the competent cadastral authorities.官方房屋坐标（HK-DE）用于明确标注已登记建筑的精确空间位置。该数据集的来源为德国各联邦州的土地登记处，即德国全境所有地块与建筑的官方名录。与通过插值计算或其他途径采集的数据不同，这套覆盖全德的超2200万条官方房屋坐标均基于实地单独勘测，并由具备资质的地籍主管部门进行持续且全面的更新维护。
