Matterport Documentation of Dome Interior Wood Engravings
The Historic Structure Report of the State House Dome included a brief history of the structure, a conditions assessment, and a complete interior mapping of all structural components. To complete the exterior and interior mapping of each component, aerial photography, laser scanning and Matterport were the technologies utilized in mapping out the dome; including its interior structure, using the latest 3D scanning methods, techniques and technologies. These technologies captured the Dome three dimensionally to a level of detail and accuracy that was unimagined only a few years ago. During this work, MCWB documented the Dome using scanners, computer software and digital documentation expertise. Each of these systems are designed to capture different kinds of data in differing environments. The exterior of the Dome was recorded using a LIDAR laser scanner capable of scanning objects up to 700 meters away from the scanner location to an accuracy of approximately 2 millimeters. These scans were augmented with photogrammetric scans from drones. The structural system within the interior of the Dome was also recorded using a LIDAR laser scanner, and a 3D photogrammetric scanner named Matterport.
