Study On The Digitization Of Weather Information In Navigation

Along with development of the computer and information technology, many expert and scholar put forward the conception of digital navigation. Supported the conception above, the thesis discussed how to map out a digital standard in navigation weather.Standard should pertinence its vocation. The thesis discuss the collective method of service of digital navigation weather bases the weather information service for navigation, and sum up weather's restrict factor and control gene in navigation. For the sake of using computer deal with the digital information, there should be a reasonable and credibility data model. By the theory and method of GIS, the thesis discuss the data model that may be use in the digital navigation weather information. Then the thesis made out a digital standard in navigation weather base on above. Finally the thesis made a conclusion by the contrasted with the original climograph and digital climograph in follow:As the result of the thesis will put forward new aspect in the research of navigation weather, and add new function in ECDIS, and made out contribute in digital navigation.
