This data is the TanDEM-X / TerraSAR-X interferometric data pair (2012-02-12) provided by the dual satellite tandem mission launched by the German space agency. The DEM with resolution of 10 m generated by gamma synthetic aperture radar interferometry software (2015 version) is fully shared. The data set contains dem2012, a total of 1 band. Data set file name and band name are as follows: data set file name: 2012 Bogda digital elevation model data set, dem2012-2012 digital elevation model of the region (unit: meter (m)).

This data is the TanDEM-X / TerraSAR-X interferometric data pair (2012-02-12) provided by the dual satellite tandem mission launched by the German space agency. The DEM with resolution of 10 m is generated by gamma synthetic aperture radar interferometry software (2015 version), and the coordinate system is UTM WGS84.
By using the platform equipped with TerraSAR-X and TanDEM-X sensors, the complex data (including amplitude and phase information) of the same ground object are obtained at the same time to form an interference pair. After accurate registration, complex interferograms can be obtained by conjugate multiplication of complex images. Based on the geometric relationship among flight platform, beam view and baseline, the phase information in complex interferogram is unwrapped to obtain the ground elevation information. The absolute accuracy in the vertical direction is better than 10 m, and the relative accuracy is 4 m at & gt; 20% and 2 m at & lt; 20%.
