Conducted by Thorsten Kahlert @ ‘Centre for Geographic Information Science and Geomatics’ at SNBE.
Test survey using DJI Mavic Pro, Drone Deploy and Photoscan Pro. Drone was flown at 80m asl with 80% overlap to front and sides. Camera angle was set at 90 degrees for nadir scan to test how well it would pick up the tree line abutting the east bank of the henge.
