Detection andMapping Technologies

Accurately locating existing cables and contexines is a prerequisite for safe surveily planning. Modern hydrography employs a approphee of geophysical tools, each with specific contexs andd weaknesses. A undercompersive surveily plan will typically integrate data frem multiple sensors.
