面向海事行业的网络海图服务总体技术模式与实验研究
|
摘要
随着海图信息价值的不断提升,海洋空间信息不再只是以航海图书产品和专题信息图件服务于固定的使用者,网络海图服务逐渐成为支撑海洋空间决策的重要基础。分析传统航海图书资料产品模式的不足,研究以基础数据资源层、关键技术支撑层、信息服务平台层、行业专题服务模式层和典型行业应用5个层次的网络海图服务总体框架,基于ArcGIS Nautical Solution和ArcGIS for Server技术,介绍实现海洋空间数据的互操作、多尺度数据管理和可视化、Web服务访问接口等网络海图服务关键技术,提出面向海事行业的网络海图服务模式。通过开发"中国北方海区海洋测绘地理信息服务平台",实现海洋空间信息在线显示与发布,为行业提供信息浏览、信息查询服务、实时动态标注,数据自动同步和共享功能。
Due to the high application value of maritime spatial information, navigation publication products are serving not only for specific user, but also for public as Web Chart Service(WCS), which has gradually become an important part of supporting space decision-making. This paper analyzes the limitations of the traditional product model of Navigation Publications product, and studies the overall framework of Web Chart Service with five levels layers: basic data resource,key technology support, information service platform, industry service mode and typical industry application. The framework is based on the technology of ArcGIS Nautical Solution and ArcGIS for Server. This paper introduces the key technologies of Web Chart Service such as interoperability of marine spatial data, management of multi-scale data and visualization, Web service access interface. Through the development of the project of "Marine Surveying and Mapping Geographic Information Service Platform of North Sea Area of China", representation and publication of marine spatial information online is realized, and the functions of information browsing, information query service, real-time dynamic annotation, automatic data synchronization and sharing are provided.
