Subject: r.contour writes negative elevations to category
Platform: Mac OSX
grass obtained from: Trento Italy site
grass binary for platform: Compiled from Sources
GRASS Version: 5.7cvs20041009
r.contour puts the contour elevations in the category. A minor drawback is that
this rounds any
fractional elevation values to integers, so is useless for fine detail contouring.
The big problem is
that it will write negative categories, which I'm told is wrong.
r.contour should write elevations to a table. It does put the elevations in
the z (height) of the
vector, but there doesn't seem to be a height option to v.to.db (just length
and area). That would be
the other solution - maybe easier to do. |

Now it writes a table with levels.
WARNING: cats are not level values any more!
