Hi Nikos,
I am going to follow your advice, and try to figure out how I can do
that :). I am taking a GIS course in this quarter but I am a Mac user
and the instructor is using the ArcExplorer for teaching. ArcExplorer
looks like so simple according to the Grass. Anyway, I have GPS
coordinates of my site and localities, and raster maps (in .tiff
format) also.
I really want to learn to use Grass for an enough level.
Thank you very much Nikos.
Peace,
Ferhat

hi everyone,
I am a first time Grass user. Grass looks like a detail software for
me, because of I am a physical anthropologist not a geologist or
geographer. I have a vertebrate fossil site and I am trying to
digitize (3D visualization) the site by Grass. I have tiff and jpg
extension of the maps. Can I use these files as a base or layer to
digitize the map, can I import it to the Grass. I am really an
amateur for Grass and GIS. I'll be a happy anthropologist :) if I
can
get some practical and basic advice from you guys.
thanks a lot,

Hi Ferhat!
First read the First Time Users section in
http://grass.osgeo.org/intro/firsttime.php
If you just need to visualize something (a single map) you can start
with an XY non-geo-referenced LOCATION and import your images. You can
create easily an xy location when starting grass. Then you import your
images with r.in.gdal module.
However, if you intend to do some geo-analysis, you definitely need
your
geospatial data to be anchored on some coordinate system.
Before doing anything:
.are your maps georeferenced?
.do you have any other referenced raster maps or vector data?
Cheers,
Nikos
