I come from a caving family but personally I spend most of my time underwater. Underwater I did a lot of 3d photogrammetry until a helicopter ride this summer caused a dry spell - so I decided to buy a UAV.
I have had 2 UAVs end up in the water and realise they are not the best tool for underwater photogrammetry so have had a play with some topside photogrammetry instead. Growing up on Mendip I know of no better place to see contrasting topography than Charterhouse, so I scanned it.

The 3d model can be found here: https://skfb.ly/6DnB8

I am currently processing some Digital Elevation Models showing altitude and slopes. I will upload these as and when they are complete.

Unfortunately I had to decimate the mesh from just under 16m faces to 8.5m faces to get it within the file size limit for Sketchfab

Looks great! Will have to boot up the computerand take a proper look.

Thanks for sharing
