LiDAR is a ranging or detection technology that uses light to measure distance to a surface or an object. In the mid-1990's the first laser scanner was developed. This technology was stable and stationary and very large in size. Over time, the technology progressed and became smaller and more mobile and eventually became small enough to mount to a drone.
"As soon as they got this technology on a drone, construction was interested."
--Joe Priestner, PE, PLS, Duncan-Parnell, Inc.
In BuilderCast's 4th episode in the Drone series we find out about the origins of LiDAR technology, and its use on drones to measure and create terrain models. The advantage of LiDAR lies mainly in mapping/modeling through vegetation, so we also asked about levels of accuracy and for clarification on the differences between photogrammetry models and LiDAR-generated models.
Finally, we asked for recommendations on the technology implementation models contractors should consider, how much it might cost, and how to get started using LiDAR technology for construction projects.
