If you wish to use the new wxGUI I would suggest to download the latest 6.4svn source code snapshot. The GUI has seen a lot of improvements. http://grass.osgeo.org/grass64/source/snapshot/ And see grass64.svn/debian/README.debian there for instructions on how to download Debian packaging rules from DebianGIS and build a .deb for your version of Ubuntu. (it is almost as simple as dpkg-buildpackage to create them using the automated scripts) or if you prefer just compile it yourself as you have been doing.

[GRASS-user] return value of modules?
Hi do the modules of R (e.g. r.stats, ...) have return values which I can evaluate to find out if the execution was successful? E.g. returning -1 when an error occurred?

[GRASS-user] Suggestions for a bit more complex network analysis
Dear GRASS-users, v.net.path is able to compute the nearest path from the starting point to the ending point on an network. I would, however, like to find the nearest end point (out of an array of end points) on a network from my starting point. Is this possible? How? My final task is to compute the cost distance for each starting point (n=486513) to the nearest end point (n=1006). Cost distances should be saved along the category of each starting point in a table so that the table would have the mentioned 486513 lines at the end. Is this possible? How? Thanks for your help.

Hello, I want to resample my categorical raster data from higher resolution to lower, using mode method. Looking at the syntax, I can't figure out where I tell the command the new resolution.

[GRASS-user] Cell limitation for raster maps; Out of memory
Hello Grass Users! My question concerns the water modules: r.flow, r.watershed, r.terraflow,... etc. But it's also interesting for other modules The rastermap from which I'm running the analysis modules has the following r.info: | | Type of Map: raster Number of Categories: 453 | | Data Type:CELL | | Rows: 3996 | | Columns: 6936 | | Total Cells: 27716256 | |Projection: Transverse Mercator (zone 0) | |N:5380887S:5372895 Res: 2 | |E:4514163W:4500291 Res: 2 | | Range of data:min = 378 max = 453 | -- Error: Out of memory My question is: Is there a generell limitation of total raster cells?

[GRASS-user] Problem converting sites and vectors
Hi folks I have a small problem. I am running GRASS 6.3 on OS X 10.5.5. When I started with these maps I was use GRASS 5.0.2. As things evolved I converted them over. Now one map set is giving me grief. My sites and some vectors haven't been displaying on this map. I tried reconverting my sites to point vectors and got: v.in.sites [EMAIL PROTECTED] output=wedgetomb8 Default database is not set Input format: dimension: 2 strings: 1 FP:0 One problem vector area gave this: v.convert [EMAIL PROTECTED] output=Lake8 endian=big -- overwrite --quiet Vector map Lake8 already exists and will be overwritten Default database is not set All my other maps are fine. There were points when I was trying to attach a database to the maps, without success. So, I am not sure if I did anything inadvertently or not. I just want to fix these so they work again. Also, if this will help diagnose the problem, the point vector file in the misbehaving map set have the following files: coor head hist While the ones that are working have: cidx coor dbln head hist topo I am planning to use these maps in my ph.d dissertation, and wold like all of them working. Can anyone tell me what is happening and more importantly how to fix it. Kurt D Springs ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user

Ok, applying my little grey cells (as Poirot would say) to the problem
at hand, I believe I have resolved this as follows:
for LAYER in `v.category -g option=report in=vect | awk '{print $1}' |
uniq` ; do
v.to.rast in=vect layer=$LAYER out=vect_$LAYER use=val
done
