		+	Go to http://srtm.csi.cgiar.org/SELECTION/inputCoord.asp, select and download the data tile for central/eastern Germany. Now cut the area of Thuringia using QGIS functions, e.g. ''Raster > Extraction > Clipper''. Therefor, using the bounding box '''x1:9.861871, y1:51.703773, x2:12.677359, y2:50.176473''' is an option. Finally, reprojct to a meter-based reference system - here we will use EPSG:32632 (WGS84/UTM zone 32N).
