Remote sensing and geophysical survey techniques represents a non-intrusive method of detecting subsurface features below the ground. Unlike traditional archaeological excavations that impact the surrounding soils, remote sensing detects subsurface features or cultural materials with little or no damage to the surrounding soil matrix.
Some remote sensing and/or geophysical techniques we commonly utilize include Ground Penetrating Radar (GPR), magnetics, resistivity, and photogrammetric mapping. These survey techniques are professionaly accepted within the historic preservation field and may provide planners a relatively inexpensive "look" into the ground before project plans are finalized. By detecting potential archaeological features early in the planning stages, project managers can avoid sensitive areas that would require costly archaeological work to mitigate the project.
