Collected sea floor data - February 2020

Olex creates sebed maps using data from the ship's echo sounder and GPS. As more depths are received, the chart becomes more accurate. The seafloor calculation is fully automatic and require no manual operation. The system has no limit in the amount of soundings which are handled. The seabed map is displayed in real time, as a 2D chart with dynamic depth contours or in 3D with a virtual camera.

Olex users are encouraged to share their sea floor data. This data sharing is free of charge and are organized by Olex AS. After sending their own sea floor data to their dealer or to Olex AS the users will get access to a database with collected depths from other Olex users all over the world.
