extracting raster elevation along an XY vector path

[Evaristo QUIROGA]

< Hello Grass Users,

< I am a Grass neophyte so I'm hoping for a little patience here. How can I

< I have learned about r.profile, r.transect, and d.profile, but none of
< these seem to be appropriate in cases where an XY vector has a large
< number (1000s) of coordinates.

< Thanks in advance,

        Dear John:

Get from the "moon" server the "g.gnuplot.3d" program. This program of Janne
Soimasuo creates 3-d images of vector maps for display with the "g.gnuplot" 
program. But the intermediate files created by "g.gnuplot.3d" are in ASCII 
format, with the X Y coordinates of the original vector map and the Z value 
from the choised elevation raster map.

                Bye,
                                Evaristo
