[GRASS-user] Hi everyone,

[Ferhat Kaya]

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
