Naachtun: the Forgotten Mayan City | FULL DOCUMENTARY
Comment: Recording and mapping, not taking things or disturbing. If you had lot of memory, cell phones with GPS, precision compass and lidar could stitch together what the humans see. And keep it in a measured 3D and time framework. No matter the trees, or paths taken. When I see you doing hand work, and disturbing things, I think “they could be using more precise subsurface 3D imaging now”. I am sure everyone wanted to take home samples, but …. recordings could last forever.
