Determination of ships safe navigation lane in the navigational information system

This monograph presents a concept of the determination and use of ship's safe navigation lane in navigational information systems. The ship's safe navigation lane is called navlane in this work and is determined from its parameters, chart data, accuracy of position identification and provisions of Collision Regulations. The work consists of an introduction, four chapters and a summary. The introduction provides a historical outline to the problem, discusses the current state of research on the determination of safe movement trajectories, finally sets the aim and scope of this work. Chapter 1 presents properties of the marine navigational information system, which combines a navigational system and an information system. The former enables estimating of own ship's position, the latter provides an image of the navigational situation. Chapter 2 includes methods of presenting cartographic objects in the navigational information system. Chapter 3 gives a definition and method of the determination of safe ship movement lane. Finally, in the last fourth chapter the reader will find practical use of ship movement lane ensuring safe navigation, accounting for the impact of the marine environment, e.g. tides, and collision avoidance. In the summary, most essential conclusions and remarks are presented.
