hey,
i still have not found any solution to convert my scanned map that is now part of the GRASS project into GeoTIFF.
I am really desperate as i need it in a referenced format for my further studies.
as r.out.gdal does not work (signal 11, remember?) is there any other way that i can try?
please help

If a Tiff +World-file is also sufficient, you could try r.out.tiff with
the appropriate switches.
Nevertheless you should get gdal working on your installation since it
is an essential import/export tool!
If you are working on suse or mandrake you could grab RPM-packages here

Here we see some documentation problem. Cite: "with the appropriate
switches." Non-geek user cant understand from documentation those
appropriate switches. I could not understand how to run r.out.gdal to
get ArcView comaptible GeoTIFF (there are too many options w/o easy
explanation of they meaning i.e. type). I used r.out.tiff but ArcView
8.3 was unable to load this tiff, but image viewing software was able
to show it.
Its very hard to be only person who uses GRASS in ESRI dominated
country if GRASS documentation does not contain examples how to easy
inport/export data to ArcGIS compatible formats. For many ordinary
users ArcGIS is synonym of GIS and thus easy data migration is a
"killer feature" (lack of it can kill GRASS, but good implemenation w
docs allow GRASS to spread in ArcGIS-only environments).
Just my 2c.
Maris.

OK, let me step in here again...
r.out.tiff --help
[...]
Flags:
-p TIFF Palette output (8bit instead of 24bit).
-t Output TIFF world file
-l Output Tiled TIFF
-v Verbose mode.
This is not that difficult to export a tiff file with world-file using
parameter -tv, if desired -p with optional compression, eg.:
r.out.tiff -tv [-p] in=mymap out=mymap [comp=packbit]
I could not understand how to run r.out.gdal to
get ArcView comaptible GeoTIFF (there are too many options w/o easy
explanation of they meaning i.e. type). I used r.out.tiff but ArcView
8.3 was unable to load this tiff, but image viewing software was able
to show it.
straight forward:
r.out.gal in=mymap out=mymap type=UInt16 format=GTiff
Again, here you have to choose "type" depending on your data to be
exported.
Its very hard to be only person who uses GRASS in ESRI dominated
country if GRASS documentation does not contain examples how to easy
inport/export data to ArcGIS compatible formats. For many ordinary
users ArcGIS is synonym of GIS and thus easy data migration is a

Certainly right! Just document your working converting steps on the
GRASS-wiki[1] and post a link to it. It will probably help lots of other
people.

If you can create a world file, try geotifcp from libgeotiff, or gdal
itself has a command to read the worldfile info and turn a tiff into a
geotiff.

For the record.
raster:
http://grass.ibiblio.org/grass60/manuals/html60_user/r.out.arc.html
Including examples on how to load maps into ArcGIS 8.3 & 9.
vector:
http://grass.ibiblio.org/grass60/manuals/html60_user/v.out.ogr.html
Including examples on how to export ESRI shapefiles.
Yes, r.out.gdal's help page could use a GeoTIFF example.
Documentation fixes and additions welcomed; submit to the bug tracker,
preferably with HTML tags.
Patches are even better (diff -u oldfile newfile), attach rather than
cut & paste into bug window to preserve formatting please.
best,
