| Description |
Developed and published by the German Remote Sensing Data Center (DFD) at the German Aerospace Center (DLR) as part of the TanDEM-X mission and the HydroSHEDS v2.0 project, this global vector dataset (TDM_COASTLINE / Version V1, released 2025-10-06) delineates the high-resolution boundary between terrestrial and marine environments at a minimum point distance (spatial resolution) of 10 m. Derived from the global TanDEM-X Digital Elevation Model (0.4 arc-second / 12 m posting) acquired between 2010 and 2015 (12/2010 – 01/2015), the dataset was generated through automated shoreline extraction followed by manual verification and hydrological refinement. It represents global continental landmasses and islands as Polygon / MultiPolygon features to refine DEM coastal boundaries and define the outer extent of watersheds and river outlets. |
