Maritime Borders of the Federal Republic of Germany

The maritime borders dataset contains the seaward boundaries of the Exclusive Economic Zone (EEZ), the territorial sea and the baselines. They are condensed coordinates of the maritime border maps 2920 (North Sea) and 2921 (Baltic Sea). They are coordinates compressed (interpolated) to geodetic lines. The distance of the nodes on the geodetic connecting lines of the defined boundary points is less than or equal to 100 m. The maritime borders of Germany were proclaimed in the today no more usual coordinate system "European date 1950 (ED50)". This definition is based in particular on the announcement of the Federal Government's proclamation of 19 October 1994 on the extension of the German territorial sea (BGBl. I p. 3428) and the Federal Republic of Germany's proclamation of 25 November 1994 on the establishment of an exclusive economic zone (BGBl. II p. 3769), which are decisive with regard to the demarcation of the German territorial sea and the German exclusive economic zone. In order to be able to better use these boundaries in today's GIS systems and to avoid conversion errors, the Federal Maritime and Hydrographic Agency has derived the present usage coordinates in WGS 84. In this respect, they are not official maritime borders of Germany.本海事边界数据集收录了专属经济区（Exclusive Economic Zone，EEZ）、领海及基线的向海边界。其数据源自编号2920的北海海事边界地图与编号2921的波罗的海海事边界地图的精简坐标集。这些坐标已针对大地测量线进行压缩（插值）处理，已定义边界点的大地测量连接线上的节点间距不超过100米。德国海事边界最初采用现已不再通用的“1950年欧洲大地坐标系（European date 1950，ED50）”公布。本数据集的定义尤其依据两项联邦政府公告：1994年10月19日发布的《关于扩大德国领海的公告》（载于《联邦法律公报第一辑》（BGBl. I）第3428页），以及1994年11月25日发布的《德意志联邦共和国关于设立专属经济区的公告》（载于《联邦法律公报第二辑》（BGBl. II）第3769页），这两项公告是德国领海与专属经济区划界的决定性依据。为便于在当代地理信息系统（Geographic Information System，GIS）中更好地使用上述边界并避免坐标转换误差，联邦海事与水文局将其转换为当前通用的世界大地测量系统84（WGS 84）坐标系坐标。需特别说明的是，本数据集并非德国官方海事边界。
