Description :

Greenland Ice Sheet Velocity 2014/15 from SENTINEL-1 data acquired between 2014/10/01 - 2015/09/30.

Comments :

Greenland Ice Sheet Velocity - 2014/2015: 250m gridded velocity map, generated applying coherent and incoherent offset tracking using SENTINEL-1 data acquired between 2014-10-01 and 2015-09-30.

This data set is part of the ESA Greenland Ice sheet CCI project. The file is including all measurements and annotation.
It provides components of the ice velocity, along with maps showing the horizontal magnitude, valid pixel count and uncertainty (based on the std.) within a NetCDF file.
The ice velocity map is provided on a polar stereographic grid (EPSG 3413) with 250m grid spacing.
The horizontal velocity is provided in true meters per day, towards Easting (x) and Northing (y) direction of the grid. The vertical displacement is derived from a digital elevation model.
The product was generated by ENVEO.
