Hi Andrew

I have surveyed caves with a Zebedee quite a few years ago, before it 
was commercially available. Probably several kms of passage. That 
doesn't give me an expertise it it though :-) I use Meshlan and 
CloudCompare to view and manipulate the point cloud data.

This youtube video if of the Cliefden Main Cave Survey using the Zebedee 
https://youtu.be/o7otVG2cKD4
The data in here is downsampled quite a lot but still shows cars and 
trees on the surface. The cars on the surface just under the big tree 
gives a bit of scale.

Also surveyed a few other caves at Cliefden and at Wombeyan surveyed the 
entrance of Victoria Arch, and Wollondilly and Junction Caves. Also 
surveyed a quarry on the surface at Wombeyan Caves.

What did you want to know?
