I now see the contours in the raster map as well as in the original vector file. As for the null projection, thanks for pointing it out (I was not aware!) but since the purpose of the exercise was to create an elevation profile from tabular data perhaps it is not critical. So I went ahead with the original purpose, i.e. to create an elevation profile for the track.

Then went ahead with: r.profile -i [EMAIL PROTECTED] output=- null=* I followed the track with the left mouse button and a two column list of values was printed on stdout, the distance and the elevation. Success! My only remaining question is: Is there a way to use the track raster file to input the values instead of using the mouse, so that the process can be more or less automated? Thank you all for your great help. I'll write a summary and post it in the Wiki as an FAQ or short tutorial as suggested by Markus Neteler. grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user -- View this message in context: http://www.nabble.com/Elevation-profile-from-intersecting-shapefiles%E2%80%8F-tp20744104p20844940.html Sent from the Grass - Users mailing list archive at Nabble.com.
