hi,
I had some trouble with my system. Glibc wouldn't compile and I thought a
messed up system might be the cause of my problems with grass. I finally
fixed it, but my grass problems haven't changed.

Hello everyone.
A simple question, but I'm getting mad with it!
I simply have to convert a vector line to raster. I've done it many

The output is simply blank (MAX and

Damn! So it was simply a problem with the attribute table. In the
meantime I've solved doing a moving average on the rasterized polygon,
and extracting only the cat values between the inside and the
outside... Not a straightfarword solution :)
