SEARCH, together with VCTO Labs, is conducting detailed infrastructure documentation of key facilities for the Hawaii Department of Transportation (Harbors and Highways). Over the course of two weeks, the team integrated 360-degree imagery, photogrammetry, and LiDAR, as measurable data to document the Port of Kahului on Maui; the iconic Aloha Tower in Honolulu Port; and the John H. Wilson Tunnels (built between 1954-1960), including the tunnel, plenum, ventilation shafts, highway, terrain, and ventilation building.
Drones, crawlers, and the vehicle-mounted Leica Pegasus system captured these data over a few days in harmony with operational needs and traffic in the air, on the water, and on land. The Pegasus is a unique sensor that is portable and captures data with one-centimeter accuracy up to 190 meters from the sensor and 360 degrees out at speeds of up to 45 mph The data are easily rendered for engineering and planning but can also be used for public outreach.
This work demonstrates an emerging need related to infrastructure and planning, which commenced with the documentation of the iconic Alcatraz Island in San Francisco Bay. VCTO Labs, with some assistance from SEARCH, conducted a detailed three-dimensional interior and exterior survey with LIDAR and photogrammetry of the island’s structures, roads, and open spaces. The rendered data will aid ongoing operations and management of nearly two centuries of infrastructure situated within a hostile marine environment and home to millions of visitors annually.
