-  * **gemgeomorphometry\_90m\_wgs84** contains 26 subfolders labelled in accordance to the geomorphometry layer name (see table 1 in publication). Each subfolder contains 57 tar. In each tar there are from 1 to 37 tif. Each tif (90m resolution; extend 5x5 degree) contain one band. The full size for one geomorphometry variable is 4-80G for a total of 1148 tiles. The data type for the tif is type Float32, which ensure maximum precision. +  * **gemgeomorphometry\_90m\_wgs84** contains 26 subfolders labelled in accordance to the geomorphometry layer name (see table 1 in publication).

-  * **gemgeomorphometry\_pangaea250m\_wgs84** contains 26 tif (250m resolution; extend full globe). These files are prepared for global analysis and/or to be ingested in web-GIS platform. The file size for each tif can is 100M-6G. The data type for this file is Int16 or UInt16 and the pixel value has been multiplied by a scaling factor reported in the geotif as metadata. It is possible to obtain the scaling factor using //​gdalinofo//​. To obatain the orginal value multiply the tif by the scaling factor. ​Nontheless ​for maximum precision use 90m or 100m resolution ​that are stored as data type Float32.  +  * **gemgeomorphometry\_pangaea250m\_wgs84** contains 26 tif (250m resolution; extend full globe).
