چکیده انگلیسی
The primary objective of the German TanDEM-X mission is the generation of a globally available, highly accurate and detailed digital elevation model (DEM), with the final product having 12â¯m posting, 2â¯m relative and 10â¯m absolute vertical accuracy. The first version of this global DEM has been finalized by the German Aerospace Center (DLR), in September 2016. Our experience with the experimental application of non-local means filters to TanDEM-X data suggests that TanDEM-X has the potential of producing DEMs of even higher resolution and accuracy. The goal of this investigation is to explore the possibility of employing non-local InSAR filters to achieve an effective resolution of 6â¯m, with an equivalent posting, and a relative height error below 0.8â¯m, i.e. an increase of quality by a factor of 2â¯Ãâ¯2 in resolution and a factor of 2â¯m/0.8â¯mâ¯=â¯2.5 in height accuracy - all in all one order of magnitude.
