Daily briefing
A peer-reviewed paper published on 3 November describes a low-cost ground-based survey method using a spherical camera and ground control points at archaeological sites where drone photography is unavailable or restricted. The authors report photogrammetric results and comparisons with conventional survey sampling and drone-derived imagery.
The method gives survey teams a documented fallback when access, airspace or heritage-site rules exclude flying; it is not equivalent to an unrestricted aerial view.
Check control-point geometry, occlusions, processing effort and the specific site's permissions. Comparability reported by the authors is study-specific.
