It appears to be off by quite a bit, as the terrain area is not recognizable. Zoomed out it is fine. Probable coordinate system error?

The KML can be downloaded for Google Earth use from the Fusion Table: <a href="https://www.google.com/fusiontables/DataSource?snapid=S338390f4tn" title="Carolina Bay Octant LiDAR Survey Index" rel="nofollow">. The green placemarks represent LiDAR tile sets in 1/4º x 1/4º grids. The network links to the LiDAR are visible in the kml; feel free to use these for any non-profit work. - Michael Greetings:
