Description

The dataset consists of: three orthophotos and DEMs derived from Stereo Geo-Eye and Worldview imagery; and two velocity maps derived from TerraSAR-X imagery.
The DEM-orthophoto pairs cover the debris-covered tongue of Ngozumpa Glacier at 5m horizontal resolution for 9 June 2010 (GeoEye-1), 23 December 2012 (GeoEye-1) and 5 January 2015 (WorldView-3).
The 'annual' velocity map is based on feature tracking on images acquired on 29 January 2015 and 5 January 2016. The 'velocity difference' map shows the difference between the 'annual' values and velocities derived from images covering a minimal 'winter' period: 19 September 2014 to 18 January 2015.
