SRTM elevation

Corine Landcover

Download the CLC 2006 - 100m dataset from http://www.eea.europa.eu/data-and-maps/data/corine-land-cover-2006-raster-2. The resulting GeoTiff file you can load into QGIS. Use Raster > Extraction > Clipper to cut in advance. Extent coordinates of x1:4311011.14124, y1:3172437.46652, x2:4508461.13837 and y2:3009522.44988 would be a good choice in order to keep the area of Thuringia. At the end, reproject to the target spatial refernce system (Raster > Projections > Warp) - in our case EPSG:32632 (WGS84/UTM zone 32N).

Harmonized World Soil Database

HNZ Gauging stations

Search http://hnz.tlug-jena.de/aktuelle-situation/thueringen.html for gauging stations Rappelsdorf and Hinternah and create a simple text file that contains at least the station coordinates and a whole-number identfier. A header line is advised:

id, name, lat, long
42151, Rappelsdorf, 50.49646395, 10.72495857
42160, Hinternah, 50.51864038, 10.79306017

Using Layer > Add delimited text layer in QGIS, you can easily import the stations as a layer and convert it into a Shapefile as required by GRASS-HRU: Right-click on imported layer and save it to a new Shapefile. Do not forget to specify the desired target coordinate reference system, here EPSG:32632 (WGS84/UTM zone 32N).
