📌 Single vs Array GPR Single channel pros: - Anomalies can be field marked immediately. - Better maneuverability. - No positioning data needed to do work. Do not need line of sight to a total station or site conducive for GPS. - Able to consider “visual clues” during survey e.g., old utility marks, trenches, test holes/road repairs, valves, manholes, metallic plates, speed bumps etc. - Real-Time Field Sketching or Mapping with GPS with ViewPoint software Array/ Multichannel (MCGPR) pros: - Safer - No workers exposed to traffic, no interruption to traffic from closures. - No interpretation in the field means less reliance on the skills of the operator. - 3D visualization enabling 3D deliverables. - Extremely high data density resulting in high resolution images in complex utility corridors. - Better data quality – more features detected. Better ability to determine shapes e.g.,, vaults, buried MHs. - Better ability to locate trenches. - Always permanent georeferenced data. #impulseradar #gpr #groundpenetratingradar #mcgpr #raptorgpr #pinpointrgpr
