Download Procedure

Geomorpho90m is a set of geomorphometric variables derived from MERIT-DEM. The are available at 3 resolutions:

  • 100 m resolution, under Equi7 projection.
  • 3 arc-second (~90m) resolution, under WGS84 Geographic Coordinate System.
  • 7.5 arc-second (~250m) resolution, under WGS84 Geographic Coordinate System.

The layers can be downloaded from The download can be done by clicking procedure or by command line scripting routine. The last one can be achieved by by following the Google Drive procedure authentification at You will need to authenticate reclone with your Google Drive account and then share the geomorphometry_v.1.0 folder with your own Google Drive. Afterwards, you will be able to mount your Google Drive and access directly to the geomorphometry_v.1.0 archive. Each layer folder contains 60-80Gbyte, so you will need a fast connection to download the full archive.

Tiling System under WGS84 Geographic Coordinate System

The Tiling System under WGS84 follows the same nomenclature and tile extent of the MERIT-DEM. Detail information can be found in (see Data Description). MERIT-DEM Tiling System (source Day Yamazaki)
