Geomorphology Calculators — Earth Science
Terrain analysis and DEM work: slope and aspect angles, contour intervals, DEM resolution to ground distance, resampling and smoothing, and drainage basin shape factors. Resolution to ground distance is worth running first, since it bounds what any later terrain metric can actually resolve.
