Using the latest 3-D laser scanning technology, Erdman Anthony collected archeological data from the first President's House located in Philadelphia, PA.

Philadelphia archeologists from the National Park Service had unearthed a key piece of history on Independence Mall in Philadelphia. After two months of digging, archaeologists 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 3-D laser scanning technology to gather electronic images of the site. The benefits of laser scanning survey services include highly detailed 3-D 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 also increasing the level of detail collected. This higher level of detail proves invaluable; should the NPS request additional data from the site, it is not 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, was destroyed in 1832.
