TCarta, MG3 & Satellite Derived Bathymetry

  • Introduction to Satellite Data

    In addition to its financial attractiveness, satellite derived bathymetry became instantly popular for several reasons with businesses operating in the coastal zone. Safety is the primary one, as the technique requires putting no boats or personnel in the dynamic and dangerous near-shore environment. Just as importantly, damage to the environment is eliminated since the remote sensing process does not involve contact with the water or shore. “There are no airspace concerns with satellite imagery,” added Flemmings. “The DigitalGlobe satellites fly high above airspace restrictions with almost daily access to every spot on the Earth’s surface.”

    Based in Warminster, England, MG3 is a marine geoscience survey firm serving clients worldwide. MG3 maintains a fleet of three multi-role DP1 vessels capable of operations in the offshore and coastal areas.The TCarta product appealed to MG3 because the satellite imagery could provide accurate seafloor depth data in the shallow coastal areas where it’s often too risky to take survey vessels or tow costly equipment even a few meters below the surface.
