Re: [GRASS-user] Error while onitializing GRASS6.4 with wxpython

Re: [GRASS-user] g.region (was v.to.rast conversion)
Hi Markus, I'm not using the GUI because I need to use GRASS as automated tool to convert a shape file to a raster in GTIFF. I tried to do what you have explained in many ways but without success. I know that I have to execute something like: v.in.ogr ... v.to.rast ... r.out.gdal ... But the v.in.ogr returns the g.region error also with the location= option. I tried to do another operation (maybe simpler), like reading a raster image and get information on the region, diong: r.in.gdal -o -e input=$HOME/raster.tif output=grass_rast location=$LOCATION Then setting the new location (as you suggested) and running the g.region g.region -p and this is the output: Location test created 100% r.in.gdal complete.

[GRASS-user] v.out.ascii output modification
Hello everybody, As the title says, I'm trying to use r.profile with the output of r.drain. I know I cannot use directly the output, and instead I need to transform r.drain to a vector line and transform it to a ascii point file (v.out.ascii). So, when the output form r.drain has been transformed to a ascii point file, I cannot use it because there is a third column (the category) preventing me from piping it into r.profile. I tried deleting the category but this doesn't work. I can always use awk to delete characters in the ascii file that I don't need, but I was wondering if there is a quicker way to do it. Basically what I need is to get from this ascii point file: X Y CAT xxx|yyy|1 xxx|yyy|1 to: XY xxx|yyy without using a awk-like method. Is it possible?

Hi, Giacomo Piva wrote: Hi Markus, I'm not using the GUI because I need to use GRASS as automated tool to convert a shape file to a raster in GTIFF. The GUI is good to develop and debug the script before you create an automated tool that may produce bogus results. I tried to do what you have explained in many ways but without success. I know that I have to execute something like: v.in.ogr ... v.to.rast ... r.out.gdal ... But the v.in.ogr returns the g.region error also with the location= option. Then try a valid location to start with, as explained by Glynn. I think you can use any valid location, also one of the sample datasets. When using an existing valid location, it should be enough to give the location name and mapset name as in your script. Then do v.in.ogr -oe location=$LOCATION That obviously only works properly if there is a *.prj file accompanying the *.shp file, otherwise you end up with a xy location. In the absence of a *.prj file you must either ask the authors of the shapefile or guess and manually create the location with the correct projection info.

Re: [GRASS-user] V.overlay very slow
By the way, i don't know if what i've done is correct and can be a usefull trick, or it's a rookie mistake, or a casuality. I hope someone knows why this happens, and could help anyone. This is: After trying the v.patch, v.clean(break,rmdupl), v.build thing, it was the moment to create a new column for all geometries, in order to run v.dissolve. Then, v.dissolve doesn't worked.
