[GRASS-user] v.to.rast

Hi,

I have a problem with v.to.rast. I have a vector of an Italian region (Campania), when I convert it to raster I lose the quality of boundary. Is it a problem of resolution? How can I fix the problem?

Thanks,

Salvatore

If you want to convert the boundaries to rasterized lines instead of
the area, you would first need to convert the boundaries to lines and
then convert the vector lines to raster.

Also make sure that the computational region is correctly set (extents
at least overlapping with the vector map and the desired resolution).

Dear Salvatore,

I have a similar issue. Did you fix the problem?

Cheers.
