I can't believe it, it feels way too easy using it. I just download data files from my state university website, unzip them with 7-Zip, and open them with FugroViewer. If there is any cellar hole, I can clearly see it, and will take a screenshot of the lidar map, save it, and overlay it in Google Earth. I thought it was too good to be true, and that the things on the lidar weren't really cellar holes. They don't appear on any historic maps from the 1850's onward. Sure enough, I went to some spots I found, and there was a pre-1850 cellar hole on each one (even one that was almost completely caved in). I prefer it to map overlays now, because I can find better cellar holes that were abandoned long before the map was made.
