The high res (1m or better) lidar data from the UK environment agency, that I've long wanted in FG but it doesn't look convenient to stream directly, have both DSM (surface) and DTM (terrain), theoretically allowing vegetation and buildings to be fairly directly determined including their height above the terrain...
