(2022) The dataset presented here contains a global mapping of surface ice flow velocity and the ice thickness of glaciers around the world. Glacier surface flow velocities were calculated using *Sentinel-2/ESA*, *Landsat-8/USGS*, *Venμs/CNES-ISA*, *Pléiades/AirbusD&S* and radar data from *Sentinel-1/ESA*. *Reference and link to RGI*: The Randolph Glacier Inventory (RGI) is used to define the glacier outlines. This inventory provides global glacier outlines compiled from maps, aerial photographs and satellite images and can be found [here](https://www.glims.org/RGI/rgi60_dl.html). *Projections* : UTM (EPSG:326XX for the northern hemisphere and EPSG:327XX for the southern hemisphere) and Polar Stereographic (EPSG:3031 for Antarctica and EPSG:3414 for Greenland) Data are posted at 50 m horizontal spacing. Data are provided as geotiff `.tif` that can be opened in geographic information system. The naming convention is `VAR_RGI-X.Y_date.tif`, where: - `VAR` is the type of variable contained in the geotiff, - `RGI-X.Y` indicates the RGI region number with `X` (1 to 19) and sub-region with `Y`, and - `date` gives the date of the file generation. ###Ice velocity product Optical satellite images from [Landsat-8](https://www.usgs.gov/landsat-missions/landsat-8), [Sentinel-2](https://sentinel.esa.int/web/sentinel/missions/sentinel-2), [Venμs](https://venus.cnes.fr/fr) and synthetic aperture radar images from [Sentinel-1](https://sentinels.copernicus.eu/web/sentinel/missions/sentinel-1) were used globally to map glacier surface flow velocity in 2017 and 2018. 5 different variables (`VAR`) are provided to describe : - `V` the magnitude of the ice velocity in m/year, - `VX` the component of velocity in m/year in x direction (east-west; positive toward east), - `VY` the component of velocity in m/year in y direction (north-sourth; positive toward north), - `STDX` the standard deviation of `VX` individual measurements in m/year, and - `STDY` the standard deviation of `VY` individual measurements in m/year. Note : the ice velocity of the ice sheets are not provided here. The ice velocity map of Antarctica can be found here https://nsidc.org/data/NSIDC-0754/versions/1 , and the ice velocity map of Greenland can be found here https://nsidc.org/data/NSIDC-0646/versions/1 ###Ice thickness product Data are posted at 50 m horizontal spacing in georeferenced geotiff format `.tiff`. 2 different variables (`VAR`) are provided to describe : - `THICKNESS` the ice thickness model in m, - `ERRTHICKNESS` the estimated error on the ice thickness model in m Note : the ice thickness of glaciers connected to the coast or ice shelves of the Antarctic ice sheet are not provided here.
