disarticulate commented 1 year ago

qgis "saga_cmd" uses the first line "Flow Accumulation (One Step)" as the third arg; uses the second line "terrain analysis" as the first arg; and saga can interpret the command

call saga_cmd terrain_analysis "Flow Accumulation (One Step)" -DEM "C:/tmp/processing_IFOggb/9e9bc0a2c1d54316ba69daf65f2173e8/20221031ULTIMATEEPXDEVELOPMENT.sgrd" -PREPROCESSING 1 -FLOW_ROUTING 4 -TCA "C:/tmp/processing_IFOggb/32c96b8f8d004460a0f5a2dce4c2348f/TCA.sdat" -SCA "C:/tmp/processing_IFOggb/99f37c3903354678bb3a0e8551e53d0f/SCA.sdat"
