Paper Abstract

Space-borne SAR sensors are capable to measure ground elevation using interferometric (InSAR) or radargrammetric techniques. In the first case, the phase content is used while in the second case the amplitude values of SAR image are exploited. This work is focused on the analysis of potentialities of the Interferometric and radargrammetric DSMs generation using high resolution SAR imagery acquired by two of the newer satellite platforms (Sentinel -1 and COSMO-SkyMed). Eleven Sentinel-1 and two COSMO-SkyMed scenes have been processed. A full comparison and analysis has been carried for Myconos Island where a high accuracy DSM from the Greek cadastral and other DEM from digitized contours from the 1/50.000 topographic maps are available. After a first control for random or systematic errors a statistical analysis was done. Points of known elevation have been used to estimate the accuracy of the DSMs. 2D RMSE, correlation and the percentile value were computed and the results are presented.
