Direct loading of terrain data is very high on my todo list now.

I have, but I don't seem to have the code around.  It's simple to do

See the "Add surface topology" section of the manual, which describes
the recommended approach for generating such surface meshes.  This
approach avoids creating loops or duplicate stations at the same
location.
