摘要: 为适应已成熟的海洋地理信息系统和海洋遥感应用模块技术及海洋信息业务化运行的需求,迫切需要开发海洋地理信息系统与海洋遥感应用模块集成来实现海洋信息一体化服务。针对当前平台技术水平和应用模块特性,设计了开放性三层集成框架,即数据层采用基于中间插件的二级三库集成机制、功能层采用基于API,DLL,EXE,COM组件的集成模式和应用层上基于Web Services的共享机制。以中国海岸带及近海卫星遥感综合应用系统平台(MaXplorer1.0)与多元生态遥感融合与同化模块和海浪遥感信息提取模块等八大海洋遥感应用模块为实例进行数据层、功能层和应用层的集成。集成结果表明,两者的集成实现了海洋信息资源与技术的整合,为海洋信息的业务化运行提供了技术支撑。Abstract: There is urgent and necessary to integrate amarine geographic information system and marine remote sensing detection modules.On the basis of the current technology and features of applications,an opening three-layer integration framework is designed.On the data layer,the two-level three-base integration mechanism based on the plug-in technology is applied;on the function layer,the integration mode based on API,DLL,EXE and COM is discussed;and on the application layer,the share mechanism based on the clients/service is adopted.Taking the satellite remotesensing application platform of China's coastal and offshore as an example discusses the key technology of integration at different layers and in different modules,which integrates multiecology remote sensing fusion and assimilation module,surge detection module and eight other detection modules.The result shows that it is possible to realize the conformity of technology and resources after the integration,and to provide the incorporate technology platform for marine information operation functioning.
