With a typical separation between the satellites of 120 m to 500 m a global Digital Elevation Model (DEM) has been generated. The TanDEM-X 30m EDEM is a product variant of the global Digital Elevation Model (DEM) acquired in the frame of the German TanDEM-X mission between 2010 and 2014, and has a reduced pixel spacing of 1 arcseconds (arsec), which corresponds to 30m at the equator. An automated edition was developed by the Microwaves and Radar Institute at the German Aerospace Center (DLR) to have a full and clean coverage of all Earth’s landmasses from pole to pole. The TanDEM-X 30m Edited DEM has been edited in order to have a full coverage.

November 2010 zur Durchführung der Richtlinie 2007/2/EG des Europäischen Parlaments und des Rates hinsichtlich der Interoperabilität von Geodatensätzen und -diensten 2010-12-08 See the referenced specification true TDM 30 EDEM has been edited using the following DEMs for filling gaps are AW3D30, Nasadem, Lidar, REMA DEM and Arctic DEM. Data: TanDEM-X DEM Product in 30m is considered as base Product. A new Water Bodies Layer (WBL) has been calculated considering the coherence of single scenes and a watershed algorithm. The WBL is used to separete the areas to be flattened (water) and filled (voids), which are edited with different technics and saved pixelwise in the Editing Mask (EDM). The editing process has been performed fully automatically, besides the center of Antarctica < - 88°, which has been edited in polar coordinates. Quality Assurance: The quality of the edited areas depends strongly from the used references, and the complexity of the waterbodies.
