Is it possible to use 1 arcsec data for small areas? For > example, the Grand Canyon would look really cool with that kind of detail.
It would be Cool but FGFS would crawl with our current scenery scheme Probably need a distance based chunked LOD scheme or something similar for this to work well But I think we should investigate using this around airports initialy where things are usually relatively flat. This should not add many triangles overall and should add a fair bit of fidelity to the placement of visual clues where they are most important Making the entire airport object an LOD object that swapped in a lowres model at ranges over a mile or so would make a nice addittion and be a good starting test case for LOD experiments.
