Thanks a lot for your reply.
I managed to come up with something sort of like that by using
gdal_translate to a WMS service description file and then using that.
But I don't see how to get elevations from there. Have you figured that
out? I know how to get imagery, but I'm interested in elevation values.
Thanks a lot,
