Pearl Harbor's National Historic Landmarks Surveyed using Advanced Technology On December 7, 1941, the US Naval base at Pearl Harbor, Hawai’i, was attacked from the air, resulting in the loss of many vessels, including the USS Arizona and USS Utah. These ships are now under the care of the National Park Service as National Historic Landmarks. To monitor their degradation over time and provide a unique view for park visitors, a team of experts utilized advanced technology to survey the underwater and above-water structures. Multibeam Sonar, LIDAR, and photogrammetry were used to collect data from the ships, monuments, and other historical structures. The data was then tied together using Autodesk’s Strategic Projects division, providing a 3D visualization of the structures. The Sonic 2024 was used to survey most of the Arizona using a small vessel of opportunity, while the USS Utah was surveyed solely with the Sonic 2024. Due to shallow waters and the Memorial itself, a Sonic 2020 was mounted on an Unmanned Surface Vessel (USV) to survey areas the manned vessel could not reach. R2Sonic I2NS provided inertial navigation, and QPS QINSy software was used for multibeam data collection, post-processing, and PPK positioning. Additionally, LIDAR was used to scan above-water structures, while dive teams performed visual inspections and photographed the hull structures. The survey was made possible thanks to the collaboration of the National Park Service, Autodesk, R2Sonic, eTrac, Deep Ocean Engineering, Gilbane Building, the U.S. Navy dive team, and the U.S. Navy Public Affairs. The project's success demonstrates the power of technology and teamwork in preserving and honoring our nation's history.
