Thanks - looks useful.

I ended up with:

r.mapcalc and "r#..." to split 5 different rasters into RGB channels.
r.patch'ing 3x (5x r, 5x g, 5x b)

then rgb displaying the patched rasters in ps.map.

r.blend looks easier. But I'm not sure how to keep things spread evenly and looking good for >2 rasters.

Is there any deep technical reason ps.map does not accept >1 raster? I don't want to start GUI programming, but from the command line it seems like this could be a tractable first major contribution to the GRASS code, depending on the reasons it doesn't exist.

  -k.
