If you are intending to use GIS for visualization and data conversion,
maybe better to use something easy to start off, like QGIS:
http://www.qgis.org/wiki/Download#Release_2
You have GRASS plugin there if needed. But usually you should be able to
do export the files to other OGR/GDAL supported fo

Thanks Hamish,

The PERMANENT mapset is created automatically for each new LOCATION.
However, you cannot create a (new) LOCATION *under* the PERMANENT
mapset.

If I create a new location, under PERMANENT, does that coordinate system

Yes the GRASS book is very good.
I got mine from www.booktopia.com.au took a couple of weeks to get it, even
then it was bound upside down and back to front. Still a very good book.

Hi Group,
I've been plugging away with grass for a few months now and not making
progress as fast as I would like. Is there a user group (preferably in
Melbourne though Adelaide is doable) or someone who would be able to sit
down with me for an hour or two to help me through a few startup problems.
Okay. some details.
I am working in California maps. I had trouble creating a new
project/mapset, but it is working now. I used r.in.gdal to bring in the

command gdalinfo and Grass could not file the file. Even though it is

You must create two location: the first one UTM WGS84 and the second one

you import your long/lat data into the proper location and then you can
