The study was based on a 30 arc-minutes gridded global digital elevation model (DEM). Eighteen local and regional topographic variables were for the first time calculated and mapped for the entire surface of the Earth including both land and seafloor relief. The following variables were derived from the smoothed DEM: twelve curvatures (horizontal, vertical, accumulation, difference, ring, minimal, maximal, mean, Gaussian, unsphericity, horizontal excess, and vertical excess curvatures), slope, aspect, rotor, catchment area, dispersive area, and accumulation zones.
