Hi Levente, Welcome to the list :)
The questions you ask could be the subject of a GIS 1 course, especially with GRASS. There are some good tutorials on getting started with GRASS - check out here for example: http://grass.fbk.eu/intro/firsttime.php As to where you can get maps from... There are so many sources of geographical data you'd have to specify a little bit more. To be honest, though, if you're wanting to do the stuff that you describe manually, I would actually be more inclined to point you toward QGIS. QGIS seems to be easier to learn because its GUI is somewhat more... Graphical? ;) Plus, it can connect to PostGIS (Postgres) *as well as* GRASS, so if you've got your data in a GRASS database you can still access it from QGIS. Otherwise GRASS does require a lot of understanding for regional settings, coordinate systems, etc. - all learnable, but as an electrical engineer I would assume it would be quite a bit of reading due to lacking background in that field (which, of course, is understandable). That said, the tutorial I linked is in pretty good, and GRASS is very awesome, so if you think you'd rather work with it, more power to you. I'm also a big fan. Hope that helps! Daniel -- B.Sc.
