[Abstract]:Since the 21 century, with the decrease of available natural resources on land and the progress of science and technology, human beings have gradually increased the exploration of marine resources. As the first sea in China, the South China Sea is not only rich in fishery resources, but also rich in natural resources. The rational exploitation and utilization of South China Sea resources will promote the rapid development of China's economy. However, due to the complex marine environment in the South China Sea, the exploitation and utilization of resources face many challenges. In order to promote the development and utilization of the South China Sea, the Ministry of Science and Technology has set up a series of major projects to carry out relevant monitoring and research, and has obtained a large number of field observation data and research results. How to manage and utilize these data efficiently and provide information service and forecast service is the main purpose of this paper. Based on the latest research results and development trends of marine geographic information systems at home and abroad, this paper starts from the data characteristics and user needs, combines the database technology with GIS and visualization technology, and utilizes the developed information integration technology. A South China Sea integrated information service system is designed which integrates the functions of data management and query, data processing and analysis and data visualization. Based on World Windand, Java language is used to realize the function module of the system. Firstly, according to the requirement of the system, the local World Wind map server is built, and the custom map data is added and configured, which provides the basic geographic data for the system. Secondly, based on Oracle database and Hibernate framework, the dynamic environment database of South China Sea is designed and developed based on the characteristics of historical data, measured data and model data of the South China Sea, and the efficient storage, management and query of marine environmental data in South China Sea are realized. Thirdly, the functional structure of the data analysis module is designed according to the user's requirements, and some of the functions are realized, such as statistical analysis, timing analysis and thermo-salt relationship diagram. Finally, the visualization function of ocean model data is realized based on World Wind combined with multi-source data visualization integration technology. Firstly, the Unidata NetCDF standard library function is used to realize the reading of ocean model data in the system. Based on the class and interface provided by World Wind, this paper designs and develops the raster graph element, vector arrow and isoline class and its generating algorithm. In the form of isoline map and multi-layer superposition map based on 3D terrain, the visualization of ocean model data is highly efficient, diversified and specialized. In this paper, we develop a multi-source data, which integrates the marine hydrological history data, field observation data and model forecast data of the South China Sea, sets data preprocessing and storage, data storage and management, data query, etc. Data analysis and data visualization as one of the South China Sea Ocean Information Integrated Service system. It can provide accurate information service for marine fishery, exploration and exploitation of seabed resources, economic development and scientific research in the South China Sea. At present, the system has completed the development of the main function, and has started trial operation. The test results show that the system runs efficiently and stably, and the functions achieved reach the expected goal and can meet the practical application requirements.
