we can create a vect file from an ascii file which can
be displayed, but every time we run v.to.rast it
says we need to run v.support on the vect file.
we do that and the rast file is created but all categories
are the same so the raster image cannot be displayed.
how do we set the categories so that the rasterized
image is displayed.
thanks

Hi, Norm
Vector features have to be labeled, as lines, areas, or points, in order
to be converted to raster. Normally this is done in v.digit, but it is
also possible to create scripts that would build the needed dig_att file
for you. You will need to run v.support after attributing the features.
