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 a resolution of 10 m generated by the gamma synthetic aperture radar interferometry software (2015 version) is registered with SRTM, and the result is subtracted by subtracting the data. The dataset contains elevationchange2000-2012, including 1 file and 1 band. Field measurement unit: meter (m). The data time is the acquisition time of remote sensing image, 2000-2012.
Self generated.
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 a resolution of 10 m generated by gamma synthetic aperture radar interferometry software (2015 version) is registered with SRTM and subtracted. The atlas coordinate system is UTM WGS84.
After checking the accuracy of DEM in different periods, the plane and elevation are corrected by using the cosine relationship between slope aspect and elevation difference. Then, the relationship between the maximum curvature and elevation difference is used to reduce the error caused by different resolutions. The DEM registration and relative accuracy evaluation of the two periods are carried out, and the glacier elevation changes in different periods are obtained
