The cost of a ground penetrating radar (GPR) survey can vary significantly depending on several factors such as the size of the area being surveyed, the complexity of the terrain, the penetration depth required, and the specific objectives of the survey. Typically, GPR surveys are priced by square footage or line images of the area to be analyzed. Small-scale surveys covering a few hundred square feet may cost a few hundred dollars, while larger surveys covering several acres could cost several thousand dollars or more. Additional costs may include data processing, interpretation and reporting services. It is essential to consult with GPR service providers to obtain accurate cost estimates tailored to your specific project needs.
The accuracy of a GPR survey depends on various factors, including the quality of the equipment used, the expertise of the operator, and the conditions of the survey environment. Under optimal conditions, GPR surveys can achieve high accuracy in detecting and imaging subsurface features with resolutions ranging from centimeters to meters, depending on the frequency of the radar used and the depth of the targets. However, accuracy can be affected by factors such as the type of soil or material scanned, the presence of electromagnetic interference, and the depth and size of objects or structures detected. Generally, GPR surveys are most accurate when performed under controlled conditions with well-trained operators and proper equipment calibration.
