Dear Monkey,<div><br></div><div>You have several questions on your email.</div><div>Regarding you adjust your bounding box, try something like</div><div><br></div><div>g.region vect=mymap</div><div><br></div><div>If your shapefile have an attribute with the elevation, probably when you imported your map one collum is the elevation. Try</div>
<div><br></div><div>v.db.select map=mymap</div><div><br></div><div><br></div><div>Yes, you can build your elevation profile from vector map.</div><div>Give a look at </div><div><br></div><div><a href="http://n2.nabble.com/Building-digital-terrain-model-from-shapefile-td1885927.html#none">http://n2.nabble.com/Building-digital-terrain-model-from-shapefile-td1885927.html#none</a></div>

<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;"><div>More questions about inputting vector data, and viewing the maps.</div>
<div> </div>
<div>I just read in a .shp file and the Output window said stuff was imported and "topology was built"....<br><br>When I added my newly created vector output map, I was told "The bounding box of the map is outside the current region, nothing drawn". I went to the Map Display window and zoomed out a bunch, then refit the zoom to the selected map, which then made my map visible.<br>
<br>Question:<br>Is there a way to make the "bounding box" automatically zoom to the selected map? Does this have something to do with the "Starting Location" specified on the GRASS startup screen?<br>
<br>Other questions:<br>Is the elevation data automatically contained within the .shp, .shx, and .dbf files, or do I have to assign elevations to individual contour lines? (this is probably a stupid question, I've still a lot to learn about this stuff...)<br>
<br>Is it possible to create elevation profiles from vector maps or does the data have to be converted into raster maps?<br> <br>How do I define a new "Project Location (projection/coordinate system)" on the Startup screen? (this question is probably too general, I'm just fishing for more info about how these are defined and how GRASS recognizes a valid location to start using)<br>
<br>Any info is appreciated. Thanks!</div>
