Nautical Charting
TerraSond collects hydrographic survey data to produce official nautical charts. These charts, depending on their scale show seabed features, navigational hazards, harbors and bridges, tides and currents, coastline, and navigational hazards.
We have the tools to plan, collect, process and then format either in hard copy or electronically all the data required to support safe navigation. Under contract to NOAA and others we have surveyed almost two thousand square miles of seafloor in eleven years of contracting.
