Using DEM from topographic map and DEM extracted from remote sensing image, the elevation change of glacier surface at the center of glaciation is obtained through difference calculation. It only aims at the change of glacier surface elevation in Gongga mountain area from 1966 to 2015, so it will not be supplemented and improved, and fully open sharing is adopted. The dataset contains one band, elevation change 1966-2015. Field measurement unit: meter (m). The data set is mainly extracted from remote sensing images and only represents the change of glacier surface elevation at the time of remote sensing image acquisition, which is from 1966 to 2015.
