This article presents the accuracy assessment of the TanDEM-X intermediate Digital Elevation Model (IDEM) provided by the German Aerospace Center (DLR) under the project “Accuracy assessment of a Digital Elevation Model based on TanDEM-X data” for the southwestern territory of Poland. The study area included: open terrain, urban terrain and forested terrain. Based on a set of 17,498 reference points acquired by airborne laser scanning, the mean errors of average heights and standard deviations were calculated for areas with a terrain slope below 2 degrees, between 2 and 6 degrees and above 6 degrees. The absolute accuracy of the IDEM data for the analysed area, expressed as a root mean square error (Total RMSE), was 0.77 m.}, type={Artykuły / Articles}, title={Accuracy assessment of TanDEM-X IDEM using airborne LiDAR on the area of Poland}, URL={http://journals.pan.pl/Content/100888/PDF/art9_Woroszkiewicz%20i%20inni%20GiK%201-2017.pdf}, doi={10.1515/geocart-2017-0007}, keywords={InSAR, Lidar, DTM, accuracy, statistics}, }
