If you mean so that the Google Earth images will take the shape of the terrain, then probably not (at least as far as I know). I did, in the long distant past, use a system of creating a series of flat assets each about 1km x 1km containing a Google Maps image (but it would also work for Google Earth) but they were flat and could not be contoured. They were useful only for working out where to place the roads, tracks, rivers, etc.
