Hello, i'm new to grass and not shure if i'm missing something but using "r.horizon" with GRASS 6.4.0 on Windows 7 in the single point mode gives me the "Unable to set up lat/long projection parameters" error. Im using a astergdem (http://asterweb.jpl.nasa.gov/gdem.asp).
Command used: r.horizon -d --verbose elevin=asta...@test_r_horizon horizonstep=1 coord=47.113697,11.310281 dist=0.7 g.region -p projection: 3 (Längen- und Breitengrad) zone: 0 datum: wgs84 ellipsoid: wgs84 north: 50:00:00.5N south: 45:59:59.5N west: 7:59:59.5E east: 18:00:00.5E nsres: 0:00:01 ewres: 0:00:01 rows: 14401 cols: 36001 cells: 518450401 g.proj -p -PROJ_INFO------------------------------------------------- name : Lat/Lon proj : ll datum : wgs84 ellps : wgs84 no_defs : defined -PROJ_UNITS------------------------------------------------ unit : degree units : degrees meters : 1.0 The raster displays correctly when using d.rast and displays correct elevation values with r.what. Same problem when projecting raster into utm coordinates or using a smaller region within the large dem. Can't find the problem. Can anybody help me? Thanks a lot! regards Marc
