TCarta 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. TCarta 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.
