Hi, Mapserver can return the pixel values of a clicked point from raster layers with WMS GetFeatureInfo. I believe that Geoserver can do the same, but I have never tried it. But pixel value presenting elevation should probably be multiplied with some factor for getting the true ground elevation.

Ie use it like an elevation service. AFAIK, the only way to do this is WCS, returning a tiny raster image and analyzing it to extract height. Not what WCS was designed for but can anyone suggest a better way? Notice: This email and any attachments are confidential. If received in error please destroy and immediately notify us.
