Greenland SENTINEL-1 ice velocity map from winter mapping campaign of 2016-2017.
Ice velocity map of Greenland derived from Sentinel-1 SAR data acquired from 2016-12-23 to 2017-02-27. In total approximately 1800 S-1A & S-1B scenes are used to derive the surface velocity applying feature tracking techniques. The ice velocity map is provided at 500m grid spacing in North Polar Stereographic projection (EPSG: 3413). The horizontal velocity is provided in true meters per day, towards EASTING(vx) and NORTHING(vy) direction of the grid, and the vertical displacement (vz), derived from a digital elevation model (GIMP, Howatt et al. 2014), is also provided. Provided is a NetCDF file (including all measurements and annotation), with the velocity components: vx, vy, vz and vv (magnitude of the horizontal components), along with maps showing valid pixel count and uncertainty (std.).
