Advanced Geophysical Classification

---

 Advanced Geophysical Classification (AGC), provides a valuable service in reducing the number of possible UXO targets at a given site, thereby reducing the cost of dig operations.

AGC methods can be applied to detect the presence of subsurface metallic objects, including unexploded ordnance (UXO), and to characterize those objects, allowing for discrimination between genuinely dangerous materials and benign scrap. 

Multiple electromagnetic coils are used in tandem and orthogonally to collect data in three dimensions. During processing, the data is compared to an established library of known responses to various munitions. Data analysts can then determine which items most likely pose a threat to human life and so merit removal.

Developed under the supervision of the U.S. Army Corps of Engineers (USACE) and having been successfully employed in categorizing thousands of potential UXO targets, AGC has become an essential and reliable tool of modern geophysical work.

To ensure data quality of AGC work the DoD Advanced Geophysical Classification Accreditation Program (DAGCAP) was established. NAEVA, in the capacity of the AcornSI and NAEVA Joint Venture, LLC (AN JV), passed our bi-annual DAGCAP audit in February 2023, maintaining our accreditation for the next two years.
