Markus, I am using a mask so as to limit my operation. The only improvisation I did was this time to run the set on Fedora14 as I have my dual boot machine. Luckily I have now my r.cost raster built. But, before going for that I reduced the SRTM altitude values to range between 0-255. So, some economizing on bit size was possible. But, But, now I am stuck with a new thing and this is with r.walk. I am still performing this operation on F14. But, there is a crash everytime. The input rasters are the two one the same rescaled raster for base values and r.cost generated raster for friction values. But, it is crashing every time. I am not getting a headway. I need to generate a route between two cities cross the Hindukush mountain ranges in Afghanistan. Any, ideas to this issue. I am thinking of using r.slop.aspect raster for friction values what do you suggest.

I am presently working with QGIS for my internship project and I have encountered the problem of overlapping point features, representing the entreprises that were geolocated according to their postal address and often at the street level. The functionnality of this plugin could be the solution. Since it doesn't seem to be part of the core plugins of QGIS I am looking for a link allowing me to download its sources. I tried the link proposed by Marco Hugentobler (www.hugis.net/point_displacement_renderer.tgz) but it is no longer valid. I would highly appreciate your helping me out.

You could checkout the sources with subversion (svn co https://svn.osgeo.org/qgis). The plugin code is in the folder ssrc/plugins/point_displacement_renderer. Regards, Marco Am Montag, 11.

I am still performing this operation on F14. But, > there is a crash everytime. is it the the same G_alloc() error message? if not, what does the crash report say? if so it means you do not have enough memory, which usually happens when the raster region/resolution is set to crazy values. As Markus asked, what does the region information from "g.region -p" say? Is it more than ~ 40000x40000 rows and columns?
