Accuracy assessment of the global TanDEM-X Digital Elevation Model with GPS data
, 2018 The primary goal of the German TanDEM-X mission is the generation of a highly accurate and global Digital Elevation Model (DEM) with global accuracies of at least 10 m absolute height error (linear 90% error). The global TanDEM-X DEM acquired with single-

Paddy-Rice Monitoring Using TanDEM-X [PDF]
IEEE Transactions on Geoscience and Remote Sensing, 2015 This paper evaluates the potential of spaceborne bistatic interferometric SAR images for the monitoring of biophysical variables in wetlands, with a special interest on paddy rice. The assessment is made during the rice cultivation period, from transplanting to harvesting time (May to October) for fields around Gala lake (Turkey), one of the largest ...
