Cultural Surveys Hawai‘i has in-house equipment and trained personnel to provide ground penetrating radar (GPR) services for historic preservation compliance throughout the State of Hawai‘i. This technology is increasingly used to detect anomalies in sensitive areas before more intrusive methods are implemented.

In 2008, CSH purchased GPR equipment including multiple Geophysical Survey Systems (GSSI) SIR-3000 with 400 MHz antennas and subsequently professionally trained archaeologists to conduct GPR surveys. The use of GPR allows gathering of survey information using non-invasive methods which contributes to the creation of archaeological inventory survey site testing strategies, conservation, and preservation through avoidance. The usefulness and adaptability of this technology is increasing as it is applied to more and more historic preservation compliance situations involving many types of ground surfaces as well as geologic and soil conditions.
