Global DEM derivatives at 250 m, 1 km and 2 km based on the MERIT DEM

Tomislav Hengl

Layers include: various DEM derivatives computed using SAGA GIS at 250 m and using MERIT DEM (Yamazaki et al., 2017) as input. Antartica is not included. MERIT DEM was first reprojected to 6 global tiles based on the Equi7 grid system (Bauer-Marschallinger et al. 2014) and then these were used to derive all DEM derivatives. To access original DEM tiles please refer to MERIT DEM download page.

If you discover a bug, artifact or inconsistency in the LandGIS maps, or if you have a question please use some of the following channels:

All files internally compressed using "COMPRESS=DEFLATE" creation option in GDAL. File naming convention:

  • dtm = theme: digital terrain models,
  • twi = variable: SAGA GIS Topographic Wetness Index,
  • merit.dem = determination method: MERIT DEM,
  • m = mean value,
  • 1km = spatial resolution / block support: 1 km,
  • s0..0cm = vertical reference: land surface,
  • 2017 = time reference: year 2017,
  • v1.0 = version number: 1.0,
