Administrative Units (Maritime Units) - INSPIRE Download Service

INSPIRE theme Maritime Units. These are condensed coordinates of the sea border maps 2920 (North Sea) and 2921 (Baltic Sea). They are (interpolated) coordinates compressed to geodetic lines. The distance between the nodes on the geodetic lines connecting the defined border points is less than or equal to 100 m. The sea borders of Germany were proclaimed in the coordinate system European Datum 1950 (ED50), which is no longer used today. The basis for this determination is in particular the promulgation of the proclamation of the Federal Government on the expansion of the German territorial sea of 19 October 1994 (Federal Law Gazette I p. 3428) and the proclamation of the Federal Republic of Germany on the establishment of an exclusive economic zone of 25 November 1994 (Federal Law Gazette II p. 3769), which are decisive with regard to the delimitation of the German territorial sea and the German exclusive economic zone. In order to make better use of these boundaries in today's geoinformation systems and to avoid conversion errors, the BSH has derived the present utility coordinates in WGS 84. In this respect they are not official maritime borders of Germany.INSPIRE主题：海事单元。本数据集包含北海2920号海疆地图与波罗的海2921号海疆地图的精简坐标。这些为经插值处理并压缩至大地线的坐标数据。连接已划定海疆边界点的大地线上，各节点间距不超过100米。德国海疆最初以1950年欧洲大地基准面（ED50）划定，该基准面现已废止。本次数据的划定依据主要为两项联邦政府公告：其一为1994年10月19日发布的《关于扩大德国领海范围的公告》（载于《联邦法律公报I》第3428页）；其二为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II》第3769页），二者均为德国领海与专属经济区划界的决定性依据。为便于当前地理信息系统对上述海疆边界的使用，并避免坐标转换误差，德国联邦海事与水文局（BSH）将其转换为世界大地测量系统1984（WGS 84）坐标系下的可用坐标。需说明的是，本数据集所提供的坐标并非德国官方海疆边界。
