Hi, Recently I used gdaldem to compute slope and aspect from a Digital Elevation Model. In the past I've used SAGA GIS to compute a more extensive list of terrain parameters but it uses a large amount of memory for heavy raster files. So I'm looking for a program (or scripts) that does the computation with GDAL or an associated project. So far I found some of the computations are implemented in Grass Gis.
I would appreciate any information you can provide. This is the list of terrain parameters that SAGA computes ( https://saga-gis.sourceforge.io/saga_tool_doc/2.1.3/ta_compound_0.html): - Analytical Hillshading - Slope - Aspect - Plan Curvature - Profile Curvature - Convergence Index - Closed Depressions - Catchment Area - Topographic Wetness Index - LS-Factor - Channel Network Base Level - Channel Network Distance - Valley Depth - Relative Slope Position Thanks, Camila Roa Graduate Research Assistant @ GCLab University of Tennessee
