[GRASS-user] problems with v.to.rast?

[Carlos Grohmann]

Hello, I just converted a vector map from boundaries to lines, and
then tried to convert it to a raster, but unsuccessfully.

here are my outputs:

v.type_wrapper.sh input=soilmu at workshop output=soilmu_lin
'type=boundary to line' --overwrite

-- Vector map <soilmu_lin> already exists and will be overwritten

I'm quite lost here. Converting to raster before changing from
boundaries to lines doesn't work, as I want only the outlines of the
polygons.

Thanks for any hint.

(PS. latest SVN, Linux)
