We have obtained 7.5 min vector soil maps where the labels are
meaningful but the category numbers vary as a function of the
quad map. Thus v.to.rast gives meaningless category numbers
with meaningful labels. How do I combine these maps into one
complete soil map for the county? V.patch and r.mapcalc work on
the category number and more or less ignore the labels. Is there
a slick way to make the labels the category # in either vector
or raster formats?
