-Bounzer- really interesting Vue images in your gallery. The one with the "Blue Marble" data is especially great! Yes- the FREE and OPEN GeoTiff format certainly would be a good start for Vue to support... -Dburdick- I honestly don't know all the issues involved with LOD models- I'm just somewhat familiar with MultiGen OpenFlight models and primarily of course with MS Flight Simulator models- as I have downloaded a LOT of them to increase the realism of my Flight Sim world. While they are in Microsoft's own LOD format- they are fairly simple to create as many people seem to be making them (Microsoft gives away an SDK for doing this...) While being able to open and correctly apply SHP files in a Geo-Referenced Terrain would certainly not be an EASY task, I think with perhaps some type of agreement with ESRI- E-on would be in a really EXCELLENT position to be a primary 3rd Party Add-On for the really Huge ESRI customer base! This would not be unlike E-On already working out deals with Autodesk and Newtek. But most importantly, I think, is that ESRI as an "Environmental 3D Data" company- and E-On as the "Artistic Landscape Renderer"- have a real potential "Marriage Made In Heaven"...
