ESRI is demonstrating an impressive little Silverlight powered widget that rendering terrain data in 3D with full interactivity. They support 2D and 3D Views, with full manipulation controls.
The imagery, street and topography base maps are sourced directly from Esri’s ArcGIS Online portal for geospatial services, data, applications and communities.
Elevation data is sourced from SRTM, GTOPO30 and GEBCO bathymetry via a new service published yesterday. The service was developed as a custom Server Object Extension for ArcGIS Server.
