To demonstrate the PCRaster Tools plugin in QGIS we're going to use it for the delineation
of catchments and streams. This tutorial presents a generic workflow for
stream and catchment delineation for areas where only open data is
available. The Shuttle Radar Topography Mission (SRTM) 1 Arc Second DEM
will be used. The workflow will be applied to the Rur catchment in
Germany.
After this lesson you will be able to:
find and download SRTM DEM tiles from the EarthExplorer website
