North Carolina is being treated to new LiDAR flights, courtesy of the USGS and the "Sandy" program. NC was the first state to fund Lidar back in 2000 and 2001, which resulted in a treasure-trove for Carolina bay affectionatos, as it presented them in their true glory. But... that early LiDAR was technically inferior to what is available today, as it was flown on 3-meter spacing and had problems getting through dense ground cover - especially in those areas that never have "leaf-off" conditions.
I am processing the new LiDAR, which is flown on 15 cm spacing, and does indeed get to bare-earth most of the time. I cut it down to 1-meter for saving, and am putting out 2-meter LiDAR tiled overlays for use in Google Earth.
Here are two examples from the Elizabethtown USGS Quad. Guess which one is which!http://cintos.net/ge/LiDARprojects/JoneslakeIncipientBay/JonesLake_LiDAR_network.kmz
