Olex is a unique navigation and mapping system developed by Olex AS in Trondheim. The system is used in fisheries, aquaculture, port work and piping, among others. Olex consists of the following three main elements:
Seabed survey and charting
Navigation tools
Plotter functions
Using data from the ship's echosounder and GPS, Olex calculates a realistic 3D seabed map, in real time.
Details:
Olex calculates a sea floor map using data from GPS and echosounder. For each new measured depth, the map improves. The survey takes place automatically and requires no operation. The sea floor map can display in 2D with contour lines or relief, and in 3D with a virtual camera which can be used to look around the seafloor. Bottom zoom is used to highlight selected depth areas. In addition comes special functions like calculation of water and bottom mass volume, and tools for searching and removal of bad measuring's.
The system works under UNIX, for the time being Linux. All software is manufactured by Olex AS, except the tide calculations which are handled by XTide2 The system runs with electronic vectorized charts. Effective use of digital charts requires fast computer processing. The chart cells are converted into an internal compact format, where they are kept in different crude scaling levels. By continuously recording depth and position the system builds a database where the sea floor is divided into squares of any resolution. The default resolution is 5X5 meter, an adjustment of today's GPS equipment, but the user can easily create new sea floor databases in any resolution down to a few cm. New measurements will result in a recalculation of the unmeasured squares in some radius from the considered point.
