Because utilities have differing materials, sizes, depths, conductivity, ground conditions, surface obstacles, and other characteristics, it is often necessary to use multiple sensing techniques to acquire an image of them. However, making multiple passes with different instruments is not as efficient as making one pass with a device that has multiple sensors. Combined with improved coupling techniques, a multi-sensor platform may lead to enhanced, perhaps automated, interpretation (better quality, lower risk) and better efficiency (less disruption and cost).
