The article analyzes the problem of converting an electronic navigational chart in the S-57 standard into a format that enables the input, rapid analysis, and utilization of information contained on the chart within a navigational decision support system. To solve this problem, a recursive discretization algorithm using quadtrees is proposed. Its properties and requirements are presented. The methodology for the area discretization process is described. Based on the developed algorithm, an experiment was conducted, and the results are presented.One of the fundamental tasks in navigation is the safe passage of a vessel from a given point to a destination. Solving this issue requires taking into account, among other things, the movement of other objects in the water area (COLREGs), the limitations of the water area itself (land topography, permissible depth, other obstacles), or the dynamics of the own ship.
It is estimated that approximately 80% of collisions in maritime traffic are caused by human error [2].
The increasing number of devices supporting the navigator’s work leads to information overload, thereby making it difficult to make the correct decisions that affect the safety of the ship. Consequently, research is being conducted on decision support systems. (…)
