Welcome to the premiere of Mapping the Unseen in 3D, where Underwater Acoustics International (UAI) takes you on an exciting journey into the world of underwater photogrammetry. In this inaugural episode, we dive into the cutting-edge techniques UAI uses—combining sonar, LiDAR, and photogrammetry—to create precise 3D models of submerged structures like hydroelectric dams. Explore the technology behind the scenes, hear about UAI’s groundbreaking Wishon Dam inspection, and get a glimpse of what lies ahead as we map the depths like never before. Join us for the start of an innovative exploration beneath the waves!
