海洋地质调查是我国建设海洋强国的战略需求, 调查产生的数据具有重要的应用价值。随着计算机技术、数据库技术和网络技术的快速发展, 海洋地质调查数据的数字化管理、应用和共享已成为衡量我国海洋科技水平的重要标志。鉴于传统WebGIS应用交互性差, 扩展再利用性能弱的缺点, 文章以南海海洋地质调查数据库为基础, 采用基于Flex技术的应用开发接口(Flex API) 和ArcGIS Flex Viewer应用系统框架进行开发, 并定制自定义的微件(Widget)在应用框架的基础上进行功能扩充, 开发部署在网络环境下的“南海海洋地质调查数据共享服务平台”, 用户能快速、便捷地获取调查数据。文章实现了南海海洋地质调查基本信息的集中管理、展示与服务, 该平台能够较好地满足地勘科技人员与管理人员对海洋地质工作信息服务的需求。

Marine geological survey is the strategic demand of our country to build a powerful marine nation. The survey data have important application values. With the rapidly developing technologies of computer, database and network, combining the ways of digital management, application and sharing of marine geological survey data has become an important indicator to measure the level of marine science and technology in China. In view of disadvantages of poor interactivity and low scalability in traditional WebGIS application, the sharing service platform of marine geological survey data in the South China Sea on the web was developed by Flex API and ArcGIS Flex Viewer, to develop widget for functional expansion based on the application framework. The users can browse and inquire these data easily. In this paper, the centralized management, display and service of the marine geological survey data in the South China Sea are illustrated. The results show that the platform can meet information service demands of marine users.
