 +  * **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 Float32, which ensure maximum precision. 
 +  * **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. Nonetheless,​ for maximum precision use 90m or 100m resolutions that are stored as data type Float32.

-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. ​  +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.
