7.5 arc-second global GeoTIFF (Geographic, WGS1984)

This GeoTIFF file was converted by Dr. Tomislav Hengl (ISRIC) from the shapefiles of the 15 terrain groups of Iwahashi et al. (2018). Thanks to Dr. Hengl, the GeoTIFF file is published here.

Polygon shapefiles for each tile (Lambert azimuthal equal-area, WGS1984)


Gray tiles: No Data

The attributes of shapefiles include not only the 15 terrain groups (GROUP; grouped by Japanese geomorphological and geological maps) but also the original 40 classes (CLASS).
The tile size is 30 degree (EW) x 20 degree (NS). Map projection is Lambert azimuthal equal-area (the central meridian and latitude of origin: the center point for each tile).
Please check the index map and download below zip files. Legend of the terrain groups is attached in the zip file.

Additional information

This study was supported by JSPS KAKENHI 15K01176.
The global terrain classification was created from 280 m DEMs using MERIT DEM (Multi-Error-Removed Improved-Terrain DEM; Yamazaki et al., 2017).
GlobCover 2009 was used to mask water bodies in most areas.
Iwahashi et al. (2018) is an update of Iwahashi and Pike (2007) (LINK to the data download site).
