Traditional laser scanning processes can have limitations when there are large, inaccessible or unsafe areas that need to be scanned. Using a drone can allow for safe scanning of this unsafe areas with photogrammetry.

Charleston Light, also known as “Sullivan’s Island Lighthouse,” is located on Sullivan’s Island, South Carolina, which is the northern access to Charleston Harbor. The lighthouse stands at 162.5 feet and was built in 1960. The unique design was chosen for its capability to withstand winds up to 125 miles per hour. Sullivan’s lighthouse was the last major lighthouse built in the United States.

PMC captured drone footage to document the weathered building for future renovations and to preserve the historic structure with photogrammetry. Capturing in 4k allows for quadrupled resolution, permitting maximum zoom, and a clean video source to work with.
