Research on Design Method of Inland River Digital Channel Map Based on Baidu Map

In view of the fact that the existing electronic channel map can't dynamically update the channel elements and the overall navigable area of the channel in real time, the ship driver can't grasp the actual situation of the channel while driving, this paper proposes an inland digital channel design scheme based on Baidu map, namely that digital channel collects GIS geographic information of channel in advance, this scheme dynamically generates the electronic fence of the channel elements in real time, displays the complex navigation environment of the inland river, and uses the Delaunay triangulation and Bezier curve fitting method to obtain the deep line of the channel, combines with the track analyzed by the historical track AIS data. The boundary is obtained from the navigational area of the channel, which can dynamically reflect the navigation information of the inland channel in real time, providing a sufficient basis for the navigation of the ship's pilot.
