SAGA.ta_slope_stability.0: SAFETYFACTOR

{"id": "SAGA.ta_slope_stability.0", "title": "SAFETYFACTOR", "description": "This tool computes a slope stability (expressed as a factor-of-safety) raster according to the traditional infinite slope model theory (see cf Selby, 1993) The resulting raster represents the ratio of resisting forces/driving forces (fs) on a potential shear plane with fs lesser 1 unstable, fs greater 1 stable. Except for a slope raster (in radians), all input variables can be specified either globally or distributed (through grids). The tool creates a continuous fs raster (values above 10 are truncated), and a binary stability grid with nodata = stable, 1 = unstable (optional).", "version": "1.0.0", "jobControlOptions":
