Abstract

Scientific research considers the efficiency of digital technologies for processing hydrographic information. The form of presentation of data in a digital model and the type of technical data carrying, on which data are registered, focused on the goal of compact saving of the results of the capture and their transfer to different partners for the selection of their software and technical problems. Such an algorithm in every competitive situation, especially in conditions of a strongly divided bottom line, should have a property to find an appropriate equivalent between the detail of reflection of the relief in this scale, which provides the same status of peaks and falls and is a priority of the minimum depth, which is intended to ensure the safety of navigation. Information about navigational problems and the camp of depths in these areas can be seen on the appropriate navigational charts. But in the surrounding areas of the sea with a folding relief of the bottom, knowledge of only point-holes is not enough for the safe navigation of ships. A more detailed picture can be taken from the digital model of the bottom topography, in order to give a more accurate description, character and understanding of the bottom navigational problems. The development of a digital model is possible based on the results of hydrographic surveys. In this article, the theoretical and practical aspects of the research and the real picture of the bottom topography of the ship-floating water areas are considered. The effectiveness of digital technologies for processing hydrographic information is rich in what lies in the set organization of digital data. For the making of the digital relief model, a tree data structure was adopted.
