Capturing History at Mount Rushmore
Throughout the first week of the project, the team has been able to complete the digital scans of the interior and exterior of the historic Sculptor’s Studio, the Hall of Records behind the sculpture, and several perspective scans of the Mount Rushmore sculpture. Scanning stations have been set up behind the sculpture to get the top of the heads as well asstations along the Presidential Trail to scan the front of the faces. A scanning tripod has also been custom made for the project to capture scans directly on the mountain. The Mount Rushmore technical ropes team was busy on Monday, May 17 working with the tripod on the sculpture before the team begins using it for scanning.
The scanning data that has been captured is the first highly accurate and comprehensive survey of the mountain. The advanced 3-D terrestrial laser scanners that are being used on the project are capable of capturing 50,000 plus dimension points a second. The highly accurate data is giving the National Park Service the opportunity to use cutting edge technology to interpret and record one of America’s icons. The memorial will use the data for not only long-term preservation planning of the historic resources, but also to develop 3-D modeling, virtual tours, and other interactive interpretive programming.
The staff at Mount Rushmore has set up an updated website about the project. To follow the scanning progress, go online at www.nps.gov/moru and click the quicklink “2010 Digital Scanning.”
