Hi
I post on facebook as YAAMAPPING. All our work is done pro bono for local and community archaeology groups. I started using P4 series cameras with filtering to look at how archaeology shows up under different filters with different light, then moved on to X3 cameras. The current one only sees blue and Near infra red which we process to get the results.
Also using a DJI Mavic 2 pro enterprise dual with a thermal camera
take a look at our posts.
