I think you should be looking at converting the shapefile contour lines

Dude- It is saturday night. Your request is for a fairly simple
operation, but there are several steps.
Some hints:
1. convert your contours into a DEM:
v.surf.rst
2. sample the elevation model along your line segments:
v.to.db
v.drape
you may need to densify the line segments-- i.e. add more v

ok, next we need to figure out why.
can you rerun with:
g.gisenv set="DEBUG=5"

It is not advisable to stay in a region of that size for very long, and
definitely don't try any raster ops. Note that most vector modules don't
care about the region settings, but d.zoom and f

Dear users
I can't project my map in a geographic projection location right into a
location with austrian lambert conic conform projection. If I try it with
v.proj GRASS just imports the ID-column twice and no other columns f.e.
coordinates, values...
Should I use another command?

Ah, right you are -- I added columns x,y,z to the table and then ran
v.to.db option=start columns=x,y,z and it worked perfectly. Many thanks!

If you are sure lines are horizontal, then you can copy coordinates of
the from-node (or the to-node, anyway) of each line to your table.

Dear Hamish,
Yes, the lines are absolutely horizontal - every point has the same
elevation. I tried v.to.db before writing to the list. But v.to.db
only has options to upload the following values: cat, area, compact,
perimeter, length, count, coor, start, end, sides, query, slope. A

In such case gis.m will emit just an warning and not change region.

I was hopping I would not have to resort to compiling everything from
source. I recall that a while ago a simple apt-get would be enough to
get everything working just fine in Ubuntu. Now that was friendly...

The maximum zoom in for the display is tied to the resolution. It
won't zoom in past the resolution. For example, if you have the
resolution set to 1km, you can't zoom in to a 100m area in the display.

Perhaps solved (I hope)!
I created a local repository (eg. /usr/local/mydebs); then I download
from Debian-Lenny all gdal packages
(libgdal1-1.5.0-grass_1.5.2-1_i386, gdal-bin_1.5.2-3_i386, etc.etc.).
I updated the repository and my sources.list as explain here:
http://wiki.clug.org.za/wiki/How_
Grass 6.3.0 on Ubuntu, give me "maximum zoom-in reached", when I tried
to zoom in to city level of data of shapefile of Indian highways
(taken from openstreetmap).
Is there any limit to zoom-in for vector files. If yes, how to reset it?
Thanks in advance.

Hi all,
troubles remain...
I removed gdal library by synaptic and then I compiled gdal and
grass6.4 svn, but the error remains.
I've also tried to remove and install everything from synaptic
(grass6.3), without improvement.
I only have one version of gdal installed.
Does someone use gdal 1.
