Research on Sea Digital Map used for Ship Navigation

With rapid development of modern electronic information technique and navigation technique, the Sea Digital Map, presenting sea geographic information and maritime traffic information in digital style, has come into being. It brought birth to a technique revolution in the field of ship navigation, and accelerated the development of the informationalization, intelligentization, and information sharing of maritime ship traffic. Nowadays, Sea Digital Map and its application systems have been the key part in Ship Integrative Navigation and Maritime Traffic Control. This thesis has made a deeply research on the data structure, accessing control, standard map symbol display of the Sea Digital Map which is met with the criterion Lt Military Digital Sea Map for Ship Navigation Exchange Format Gt of Chinese Navy Navigation Guarantee Dept. Based on the data and display separate idea, and from the point of function encapsulated independently, the thesis developed the Sea Digital Map used for Ship Navigation. It is composed of basal platform of Sea Digital Map, GPS interface, AIS interface, B/S and C/S net communication interface and ARPA frame picture overlay. It´s a Web Digital Navigation Map application platform made up with the functions of digital map display and edition, route designing, route monitoring, ship monitoring, maritime traffic data analyzing. Sea Digital Map used for Ship Navigation could be used widely in such fields as ship navigation, maritime transaction, maritime safety traffic management, sea function planning management, etc. This thesis gives a detailed introduction about Sea Digital Map used for Ship Navigation from the point of the composition and realizing technique.
