Drone surveying promises speed and efficiency, yet many fleet managers face choice paralysis. Should you invest in accessible photogrammetry systems or pay a premium for LiDAR (Light Detection and Ranging) sensors? While the decision is often driven by cost, it ultimately comes down to physics.
Comparing LiDAR and photogrammetry for earthwork accuracy, cost, and workflow comes down to one key difference—active measurement versus passive imaging. One captures structure; the other captures surface.
