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
depht areas. In addition comes special functions like calculation of water and bottom mass volume, and tools for searching and removal of bad measurings.
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 easlily 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.
