TCM aggregates bathymetric data from a wide variety of sources: navigational and bathymetric charts, ship trackline data, LiDAR surveys, satellite imagery, optically-derived, and sonar surveys (multibeam and single-beam).

Global Bathymetric Data: We Show You the Bottom of the Sea
TCM is the world's foremost supplier of bathymetric data for near-shore areas around the world. Our data fill the gap between low-resolution data sets and the highly accurate but limited coverage provided by hydrographic surveys.
TCM data provide a level of detail that approaches that of survey data, but at a fraction of the cost. Our coverage area extends over the world's entire littoral zone, from the shoreline to the edge of the continental shelf.
Our data are used in a variety of industries; oil & gas exploration and production, environmental research, archaeology, telecommunications, fishing, and many others.
