Abstract

The invention relates to a method for generating a virtual navigation mark on an electronic navigation channel chart. The method comprises: (1) providing an electronic navigation channel chart on a shipboard terminal computer; (2) determining the ship seaworthiness area in the navigation channel; (3) receiving virtual navigation mark data; 4) adjusting the ship seaworthiness area according to the received virtual navigation mark data; and (5) displaying the adjusted ship seaworthiness area and the virtual navigation mark on the electronic navigation channel chart. According to the present invention, with the method, the area suitable for the ship sailing under the current water flow condition and adjusted through the virtual navigation mark is displayed on the electronic navigation channel chart, such that whether the ship sails in the seaworthiness area can be determined so as to reduce the probability of ship accidents.

Description

technical field [0001] The invention relates to a method for generating a virtual navigation mark on an electronic waterway chart, in particular to a method for generating a virtual navigation mark on an electronic waterway chart based on real-time data. Background technique [0002] As a national strategic basic industry, shipping is an important part of the comprehensive transportation system and an important strategic resource for sustainable economic and social development. The digitalization of waterways is an important part and development trend of shipping informatization, and plays a decisive role in the safety and efficient management of inland waterway shipping. [0003] Navigation mark is the abbreviation of navigation mark, which refers to the mark indicating the direction, boundary and obstruction of the navigation channel, including river crossing mark, coastal mark, guide mark, transition guide mark, head and tail guide mark, side mark, left and right navigati...
