%K Glacier center;close-up photogrammetry
%X Close- range photogrammetry has become one of the effective methods to obtain glacier DEM. It uses non metric camera and stereo image pair to generate DEM data with large scale and high spatial resolution. Based on "2008 / T" and "gb-7930", some of the data need to be further optimized. This manual introduces the scope of use, measuring instruments, data acquisition, field processing, achievement display, precision control, etc. Mapping period to around 2010
