After running the r.los algorithm through QGIS 2.0, I'm getting a 'Problem loading output layers' box which gives the following message:
Oooops! The following output layers could not be open Output raster layer: C:/Users/ffinnm/Documents/CGE/LVIA/Southdown/gis files/viewsheds/hhh.grd The above files could not be opened, which probably indicates that they were not correctly produced by the executed algorithm Checking the log information might help you see why those layers were not created as expected This algorithm requires GRASS to be run. A test to check if GRASS is correctly installed and configured in your system has been performed, with the following result: GRASS seems to be correctly installed and configured
I have checked the log information and there is no error logged here. Interestingly, in the log information, the algorithms section states that the 'r.voronoi' algorithm ran 2 seconds after the 'r.los' algorithm. I didn't instruct the r.voronoi algorithm to run (or know what it is!).
I have also tried changing both input and output raster formats.
Any help here would be much appreciated, thanks
