Shoreline

This data set covers the shoreline of Mecklenburg-Western Pomerania (creation in the period from 2010 to 2016). It consists of the Outer Coast Line and the Bodden and Haff Coast Line. The determinations for this shoreline have been administratively determined and are based on terrestrial and satellite-based surveys of the shorelines at normal mean water level (NHN plus 1 cm and HN minus 0.14 cm respectively). The outer coastline is defined as the theoretically natural line of defence against the Baltic Sea. It represents a land-side line from the mainland coasts over the islands and peninsulas from the border with Schleswig-Holstein to the border with the Republic of Poland. The so-called “jump marks” from one section of the coast to the next are at the same time the border from the outer coastline to the Bodden and Haff Coastline. These jump marks have been set according to morphological points of view at the sites where, in the case of natural coastal dynamics and sediment transport, the hooks for the sprouts or flat coast formations would start. The specified length of the outer coast is composed only of the actual parts of the land of this line and does not include the water-side connecting lines between them. All terrestrial shorelines that have not been assigned to the Outer Coast are defined as Bodden and Haff Coast Lines. The determination of this Bodden and Haff Coastline was usually done by digitising the orthophotos of the State Office for Internal Administration of Mecklenburg-Western Pomerania (LAIV-MV) and was then replaced in some (important and accessible) sections with tachymetric surveys analogous to the outer coastline. The reference system of the situation is the geocentric, three-dimensional European Terrestrial Reference System 1989 (ETRS89), for Mecklenburg-Western Pomerania uniformly in Zone 33-North. The reference system of the height is the system Deutsches Haupthöhennetz 1992 (DHHN92). The reference selipsoid is defined as the Geodetic Reference System 1980 (GRS80). The reference area (quasigeoid) passes through the zero point of the Amsterdam level and is called the Normal Height Zero (NHN).

A continuous, homogeneous shoreline in the locality was measured, which is constant at NHN plus 1 cm or HN minus 0.14 cm regardless of the respective water level. The resources are usually not updated.
