Viaduct photogrammetry and column documentation · fixed ASL.
Connect to Red CORS → obtain FIX → establish the point in Survey → photograph the point → stop Red CORS.
Set the GNSS base on the Survey point → start Local NTRIP → start logging. On the controller, confirm Local NTRIP—or Red CORS when documenting structures.
After mission teardown, stop logging and transfer the log file to the tablet desktop.
Record the TOP, aircraft ASL and measured target surface. Identify each column or pier consistently. Separate missions / TOPs with four asterisks.
KM42 VIADUCTO S/N TOP ASL: ___ m TOP +50 m panorama · aircraft ASL: ___ m
Center panorama · aircraft ASL: ___ m Whole-viaduct top-down Column / pier ID: ___ Centered top-down + both opposite sides Aircraft ASL: ___ m Rangefinder: ___ m to ___ surface

Document each viaduct and its columns separately, in the listed order. Confirm clearance above the highest current column, pier cap, deck and equipment before capture; rangefinder distance is to the identified target surface.
