Using the latest 3D laser scanning technology, Erdman Anthony collected
archeological data from the first Presidents’ House in Philadelphia.
Philadelphia archeologists from the National Park Service had unearthed a key
piece of history on Independence Mall. After two months of digging, they
discovered the remains of the house where Presidents George Washington and John
Adams lived from 1790 to 1800.
Given the sensitive nature of the dig, Erdman Anthony used the latest 3D
laser scanning technology to gather electronic images of the site. The benefits
of laser scanning survey services include highly detailed 3D data, safer and
less intrusive field operations, and enhanced visual capabilities.
Erdman Anthony's scanners collect data at a rate of 4,000 points per second,
which rapidly reduces the data collection time while increasing the level of
detail collected. This level of detail proves invaluable; should the NPS request
additional data from the site, it is now readily available from the original
scan. This proved exceptionally valuable given that the excavation was open for
only a short time, after which the site was preserved to commemorate history.
The home, which served as the prototype for today's Oval Office, had been
destroyed in 1832.
