The Marine Meteorological Information Processing And Display System Based On Web Electronic Chart

With the increasingly fierce competition of the domestic and international shipping, to enhance the Shipping companies' competitiveness in the shipping market,Shipping companies are increasing emphasis on the management of the ship.How to ensure the operating safety of the ship is of great concern to the shipping community.However, marine meteorological conditions which the ships encounter have an important effect on ship's safety and navigation efficiency.How to obtain the meteorological information in real-time,process it and merge it into the Electronic Chart Display platform,which can provide integrated and effective information support for shore-based ship managers is very meaningful for the ship's safe management,effective scheduling and Shore-based services.This paper relies on scientific and technological support of national projects "Ship and cargo online monitoring system(scom)," raises the marine meteorological information processing and display system based on web electronic chart.This paper initially studies on the use of ArcGIS Server to release web electronic chart for the entire display platform;Then designs the FTP client program to automatically download marine meteorological,and in accordance with the type of marine meteorological information,design marine meteorological information database for the unified management of the meteorological data;third,focuses on the research of the secondary development platform of ArcGIS Server,determines the overlay program of marine meteorological information,designs the display process of the marine meteorological information;in the end,confirms the correctness and validity of the system mentioned in this paper through Experiments.The result of this paper is mainly reflected in the following three aspects:First,uses FTP network communication protocol,designs and develops automatic downloaded software of the marine meteorological information.In the absence of intervention,realizes automatic downloading and storage for the marine meteorological information.Second,realizes the integration and fusion of the marine meteorological information in the Web electronic charts,which provides a display platform by ArcGIS Server.As the same time,uses ajax technology to improve marine weather information display.Third,designs and implements marine meteorological information processing and display system based on web electronic chart,realizes the marine meteorological information sharing on network to provide users with accurate,convenient and efficient marine meteorological information services.
