INSPIRE topic Maritime administrative units. These are condensed coordinates of the sea boundary maps 2920 (North Sea) and 2921 (Baltic Sea). They are coordinates condensed (interpolated) onto geodetic lines. The distance between the nodes on the geodetic connecting lines of the defined border points is less than or equal to 100 m. Germany's maritime borders were proclaimed in the European Datum 1950 (ED50) coordinate system, which is no longer common today. The basis for this determination is, in particular, the announcement of the Federal Government's proclamation on the expansion of the German territorial sea of October 19, 1994 (BGBl. I p. 3428) and the Federal Republic of Germany's proclamation on the establishment of an exclusive economic zone of November 25, 1994 (BGBl. II p. 3769), which are relevant with regard to the delimitation of the German territorial sea and the German exclusive economic zone. In order to be able to use these limits better in today's GI systems and to avoid conversion errors, the BSH has derived the usage coordinates presented here in WGS 84. In this respect, they are not Germany's official maritime borders.
