This data is a 5m resolution DEM generated by the resource 3 satellite on December 12, 2012. After re-use to 10m, it is registered with the topographic map, and then subtracted from the data. It is fully open sharing. The data set contains 1 file, including 1 band, from elevation change 1969-2012. Field measurement unit: meter (m). The data set time is the acquisition time of remote sensing image, 1969-2012.

This data is a 5m resolution DEM generated by the resource 3 satellite on December 12, 2012. After re-use to 10m, it is registered with the topographic map and then subtracted from the data. The atlas coordinate system is UTM WGS84.
After the accuracy test of DEM in different periods, the cosine relationship between slope direction and elevation difference is used for plane and elevation correction; then the relationship between maximum curvature and elevation difference is used to reduce the error caused by different resolutions, and the registration and relative accuracy evaluation of DEM in two periods are carried out to obtain the elevation change of glacier in different periods
