Description Usage Arguments Value Author(s)
Create input maps for hydrological modeling (e.g. GEOtop, mHM) using RSAGA. Base maps are a digital elevation model and a map locating the basin outlet (defined by -1). Postprocessing includes terrain analysis (slope, aspect, curvature), flow direction and accumulation, as well as sky view factor calculation. All maps, including landcover, soil type, leaf area index (LAI) and bedrock (if provided), are stored in SAGA .srgd format. Further processing includes watershed delineation, resampling to required resolution, masking to the extent of the watershed (either for all maps or for landcover map only) and writing of GEOtop or mHM input ascii files.
