SAGA GIS
Before we combine R and SAGA, let’s first have a look at a SAGA module separately to get a feel for what we can do with it.
Task: SAGA GIS I
- Import a terrain model into SAGA.
- Import/Export
- GDAL
- Import Raster
- Preprocess the terrain model for the hydrological analysis with the
Fill Sinks
tool.
Task: SAGA GIS II
- Delinate catchment areas from the preprocessed terrain model with the tool
Channel network and Drainage Basins
. - Also calculate the flow accumulation.
