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
