We have a Web Coverage Service up that is intended to serve elevation data. This service is in a testing phase and we would appreciate feedback as to how well it works for our users.
A WCS serves up data values rather than pixels. In the case of the elevation data in is service, it is serving the heights above the horizontal ellipsoid.
