[GRASS-user] ps.map Advice

[Nick Cahill]

I use ps.map only to export vectors to postscript. I then use v.in.region to create a box to show the region for any raster data (which is what takes up all the room in your postscript output), then use r.out.tif or whatever to dump the raster as a separate tif file; then merge the two in Adobe Illustrator (which is what I use for final map composition). An extra step, but gives lots of control.
