Hi Levente,<br><br>Welcome to the list :)<br><br>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:<br>
<a href="http://grass.fbk.eu/intro/firsttime.php">http://grass.fbk.eu/intro/firsttime.php</a><br><br>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) <i>as well as</i> 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).<br>
<br>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.<br><br>Hope that helps!<br>Daniel<br clear="all">

Dear Grass fellows,<br>
<br>
<br>
I am a new member of the list. I installed GRASS on my Debian box, and have no<br>
clue how to continue. Please forgive me my ignorance.<br>
<br>
With my father, as a family project, we develop a system, that sends<br>
coordinates to a postgresql database. So far, I have some date in the<br>
database.<br>
<br>
My goal would be to SELECT some data from the database, and display it on a<br>
map. Could anyone help me how to achieve this? (no, I don't want google maps).<br>
<br>
I am an electrical engineer, and have no clue how does this Geographic stuff<br>
work, so it would be nice to have some pointers in the documentation.<br>
<br>
* How can I load a map into GRASS?<br>
* BTW... where can I get a map from?<br>
* How can I (from software) put a point in a map?<br>
* How can I do some analyze stuff like distance from 2 points (on a GUI)<br>
* other stuff will come, like mesh, etc.<br>
<br>
Yes, I am prepared to read documents! I'm sorry if all these questions are<br>
stupid, but I think GRASS is what I look for.<br>
<br>
Thank you for your help.<br>
