The TanDEM-X 90m Digital Elevation Model
"TanDEM-X (TerraSAR-X add-on for Digital Elevation Measurements) is an Earth observation radar mission that consists of a SAR interferometer built by two almost identical satellites flying in close formation. With a typical separation between the satellites of 120m to 500m a global Digital Elevation Model (DEM) has been generated."
TanDEM-X 12m (0.4 arcsec) DEM
For the DEM as well as for the 7 information layers quicklooks in a GeoTIFF (*.tif) raster format are provided, associated with a KML file for inspection in Google Earth. Additional quicklook raster files with a legend and a map border in PNG (*.png), but without an associated KML file, are available as well.
