Hello!
I'm using grass 6.1 CVS for a while and I love it - I've been teaching
ARC/INFO for years, but 10 years
ago on UNIX systems - I'm just happy to see that there is still a
system with command line and
scripting possibilities.However, I'm just not able to figure out how to cut a raster image
(subset, crop).
zoom in to the region of interest:
1. interactive d.zoom - beware of a bug:
http://grass.itc.it/pipermail/grassuser/2005-December/031624.html
2. manual with g.region
use r.mapcalc to extract this fragment into a new layer
I have a huge DTM and I woud like to get a portion of it.
I need to cut it by co-ordinates. I know that it should be simple but
I'm afraid I still doesn't have
the "GRASS mind" enough which may be needed.(Oh - another point, the projection systems and their management in
grass - wow! That's itreally great!)
Is there any guidebook out there with general howto-s?
Several of them in http://grass.itc.it/gdp/index.php
Wellcome to Grass!
Cheers
Maciek
