Description: These GeoTIFFs contain two different measurements of topographic roughness for the SAFE landscape (Wilson et al. 2007, Riley et al. 1999) These have been calculated using the raster package in R from SRTM data processed for use at SAFE (https://www.zenodo.org/record/3490488).Further details of the dataset and processing can be found at https://www.safeproject.net/dokuwiki/safe_gis/topographic_roughness.
