Yes, that's correct. However ElevationService requests are rate limited per user, so as with geocoding we recommend that you use the client side service where possible, as that ensures your access to the service will scale with your user base (ie. each user can make a 1,024 point query without impacting each other or your Web Service quota). > There appears to be no geodesic/great circle option.

Our architecture can not easily support this I'm afraid.
