IMPROVED TOPOGRAPHIC MAPPING IN VEGETATED MOUNTAINOUS AREAS BY HIGH-RESOLUTION RADARGRAMMETRY-ASSISTED SAR INTERFEROMETRY

We generated a consistent, gapless and high-resolution (12 m) topography product of the Antarctic Peninsula by combining the complementary advantages of the two most recent high-resolution digital elevation model (DEM) products: the TanDEM-X DEM and the Reference Elevation Model of Antarctica. The generated DEM maintains the characteristics of the TanDEM-X DEM, has a better quality due to the correction of the residual height errors in the non-edited TanDEM-X DEM and will be freely available.
