Archaeo-Physics, LLC is a consulting firm specializing in subsurface imaging of archaeological sites. We perform geophysical surveys to produce high-resolution maps of archaeological features, artifacts, and other patterning.
We use a variety of geophysical survey technologies, including magnetometry, electrical resistance, ground penetrating radar, electromagnetic conductivity, magnetic susceptibility, and LiDAR data processing and analysis. Subsurface mapping can guide excavation, reducing costs and maximizing the recovery of useful data. Because geophysical survey is non-invasive, it is an important tool for research and preservation on culturally sensitive or protected sites. In either case, geophysical methods can map patterning that may not be apparent in excavation on a site-wide scale and without disturbance.
Our staff has extensive experience performing geophysical surveys of archaeological sites in all regions of the United States and many locations throughout the world. In addition to serving as consultants to professional archaeologists, Archaeo-Physics maintains a strong commitment to education. Our staff engages in instruction and survey at field schools and public archaeology projects. We strive to disseminate the results of our work through publication, and online and public presentations.

Featured case studies: Airborne LiDAR
Light detection and ranging (LiDAR) is fast emerging as a cost-effective method of archaeological reconnaissance and assessment. LiDAR data makes it possible to construct an extremely accurate digital elevation model representing the surface of the earth, and show topographic patterning associated with archaeological features.
Careful processing and display of LiDAR data can reveal patterning in archaeological landscapes not readily perceptible to the naked eye at ground level. Processing and imaging that is designed specifically for archaeological analysis can often reveal patterning that is not detectable in general-purpose LiDAR-derived products. The examples presented in these case studies represent a few selected examples of LiDAR modeling conducted by Archaeo-Physics. more >>
