You can do that very easily with GMT (grdtrack).

Hi Michele,
I use PostGIS& GMT to generate such profiles.

Thanks to all for the replies.
Unfortunately I need to generate the elevation profiles within my
application, using only my own code or external libraries, but without
using external tools.

Hello Michele,
There is an interesting paper about this problem :
<http://www.geocomputation.org/1999/082/gc_082.htm>
I don't know if there are libraries implementing these algorithms for
DEM interpolation. Does anybody know if there is an open source function
to compute the coefficients of a bicubic interpolation ?
Regards,
Jean-Claude
Hello Jean-Claude,
you have pointed me to a very interesting article, I think that bilinear
interpolation can be enough simple to implement.
Regards.
