LiDAR vs. Photogrammetry – Which is the Best Option for Surveyors?

Today’s question is about replacing LiDAR with photogrammetry for surveying purposes. Can photogrammetry prove to be a feasible option?

Our caller for today, Issac is using ground-based LiDAR for surveying purposes. Regular ADU listeners might be aware of the difference between LiDAR and photogrammetry. LiDAR is an active technology costing thousands of dollars. Whereas, photogrammetry is the art of using images for making measurements. Photogrammetry is way more affordable compared to LiDAR and can help you produce lifelike and visually-appealing models.

But, what about accuracy? Using photogrammetry, can you achieve survey-grade accuracy that is comparable to LiDAR?
