Hi
Thanks.
How do I project the GTOPO30 data to get a specific region using
coordinates, say I need the region within these coordinates:
Upper Left (18.2987501, -33.6795831)
Lower Right (19.1712501, -34.0145831)

I want to compress a vector layer (in a single entity). And I do not

Hi Espen,
r.out.gdal uses the current region settings. Is it possible that you've set
a high region resolution? Then your GeoTIFF is probably being resampled to a
higher resolution, causing the file to be a lot bigger.
Best,
Daniel

Quite possible that I did something wrong with the region :-)
I just used the default when creating the new location. And that is
probably 1 meter( I am dealing with 10 meter DEM's).
Can I somehow change the region resolution once the location is
created? Or force r.out.gdal to export with a
In my opinion, the easiest way would be to set the region according to your

Ok, answering my own questions here I guess. Did not help just setting
the resolution to the correct value, but when I redefined the region
by
g.region rast=stryn_slope -p
and then did an export it all worked very nicely.
Thanks LeeDaniel!

Hi all,
I know, this is an extremely rudimentary question, but please bear with me:
I developed a bunch of scripts that I need on OpenSUSE. I was able to call
them up in GRASS by typing in their name. They were stored in the directory:
/opt/grass/scripts/
Recently I started working on a second
I put my GRASS scripts in a scripts folder that I created in my home
directory and add that to the PATH definition in my .bashrc file.
hth, If you like I can pass along a script that downloads from svn
and compiles GRASS with the r.stream libraries from add-ons. Works
fine on my ubuntu 10.04.

Probably the did not send you the entire thing since Arc coverages
have data in the info folder. Maybe if they export the coverage as an
