This is a highly detailed National Geographic article on the use of laser scanning to explore and document an incredible set of caves in China. As they explain, “The digital version of the cave is more real than real life. Real caves are dark. Extremely dark. In a big chamber, even with modern LED headlamps many times brighter than the old carbide ones, you can see 150 or so feet ahead or above, and not much more. Mist or emptiness overwhelms even the brightest beam. It’s natural to want to see more.
The scale and beauty of this work is beyond belief. The climbing videos will give you vertigo. Those people are fearless and 3D laser scanning is changing this field forever as well.
Thanks to Graham Hunter at 3D Laser Mapping for the tip and to the National Geographic for supporting this work.
