A GLobal High-Resolution Coastline Derived from the TanDEM-X Dataset

Kurzfassung

While the coast generally describes the transition zone between land and ocean, a coastline demarcates the exact boundary in-between the two spheres. The coastline as a feature is required in a wide variety of GIS applications and included in coastal, littoral or marine applications. In particular, a coastline is required to edit the digital elevation model (DEM) of the TanDEM-X mission, as it defines where ocean heights are to be filled in. To obtain a global, high-resolution coastline tailored to the TanDEM-X DEM, an automatic approach has been developed, which is complemented with manual corrections.
