Subject: Wish: r.labels for raster cats management

Raster Cats management tool needed: - write r.labels
Currently it is quite difficult to manage raster categories (text)
when generating new maps from existing raster maps.
A trivial, but mostly wrong solution is to copy the cats/ file.

As for the issue of transfering the cat file - this is similar to r.colors.
You cannot have r.mapcalc taking care of it (in general) because there are
often more than 1 file involved and then it is not clear which cats file
should be used. So the best would be to have a command similar to r.colors
with option rast which allows you to assign the colortable from another
raster file, e.g. r.labels mynewmap rast=myoldmap (it should include an
option to assign labels interactively - something like rules for r.colors,
so that you don't have to go through r.support.)

This is nothing urgent, we just want to store the idea in RT.

Thanks

Hi Brad,

just discovered my old report... maybe with the new r.support
things become possible?

thanks
Markus
