House coordinates

House coordinates assign an exact position to each unique building address. The Bavarian Survey Administration has more than 3.3 million current house coordinates available. House coordinates can be selected by administrative units (country, district, county, municipality), postal code areas or spatial delimitation. Optionally, complete data (all HK of the selected area) or differential data (only the newly created, modified or cancelled HK since the last update) are provided. A selection according to quality levels (A, R or A+R) is possible. In addition to the specified reference systems, a delivery in the system DHDN (geographic 2D) (EPSG:4314) is also possible.房屋坐标可为每个唯一建筑地址赋予精确的空间位置。巴伐利亚测量管理局（Bavarian Survey Administration）现拥有超过330万套有效房屋坐标数据。 可通过行政单元（国家、大区、郡、自治市）、邮政编码区域或空间划定范围筛选房屋坐标数据。可按需提供完整数据集（所选区域内的全部HK）或增量数据集（仅包含自上次更新以来新增、修改或注销的HK）。支持按照质量等级（A、R或A+R）进行筛选。除指定参考坐标系外，还可提供采用DHDN（二维地理坐标系，EPSG:4314）格式的数据交付。
