Who needs this?
DOT agencies, utility corridor programs, municipalities mapping signage and pavement, and firms doing city-scale digital twins where drone coverage alone would take too long.
Accuracy expectations
Typical absolute accuracy in open sky: roughly 2–5 cm — degrades in urban canyons and under bridges where GNSS multipath increases. Plan for control overlays where needed.
Drone vs truck
Drones excel at limited areas and vertical faces; trucks excel at linear miles and consistent lane-centered coverage. Many projects combine both.
