Ice velocity map of Icelandic glaciers derived from Sentinel-1 SAR data acquired from 2014-10-01 to 2020-12-31. The surface velocity is derived applying feature tracking techniques. The ice velocity map is provided at 100m 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), is derived from a digital elevation model. Provided is a NetCDF file with the velocity components: vx, vy, vz and vv (magnitude of the horizontal components), along with maps of valid pixel count and uncertainty (stdx, stdy). The product was generated by ENVEO. The generation of this data set and its scientific interpretation are discussed in the following citation.
