DTM steepest descent and ascent tessellation Korcak exponent islands catchments mountains

DTM

steepest descent and ascent

tessellation

Korcak exponent

The aim is to compare the geomorphometric signatures of catchment basins (using Steepest Descent lines converging to Outlets, SDO) and mountain ranges ('massifs', using Steepest Ascent lines Toward Summits, SATS) on a set of islands in various topographical, geological and morphoclimatic settings:
