    A real-time access technology for massive dynamic heterogeneous spatial information

    • 摘要: 随着全球经济建设和社会发展,社会各界对互联网空间信息的需求日益广泛.通过分析动态异构空间信息特征及来源,建立空间数据自组织规则,采用互联网信息地名识别与内容整合技术、万个级用户协同标绘技术、基于虚拟资源池的动态异构空间信息存储技术、空间数据的自适应显示技术和断点续传的要素级数据更新机制,对海量全球动态异构空间信息实时接入方法进行原型设计.结果表明: 海量动态异构空间信息实时接入技术解决了标绘信息的实时传输,实现了多尺度下的标绘数据的实时/准实时显示,确保了海量空间信息资源服务的实时性和可读性.

       

      Abstract: With the development of global economy and society, international spatial information is needed by community increasingly.The features and sources of dynamic heterogeneous space information are analyzed and, on such a basis, organizational rules of spatial data are established.Using international place names identification and content integration technology, tens of thousands of users' collaboration plotting, dynamic heterogeneous spatial information storage technology based on virtual resource pool, adaptive display of spatial data and mechanism of breakpoint continuingly element level data updating, the authors prototyped the method of massive global dynamic heterogeneous spatial information real-time/near real-time access.The design and research results show that the real-time access technology for massive dynamic heterogeneous spatial information solves real-time transmission of plotted information, realizes the real-time/near real-time display of plotting data on multiple scales and ensures the real-time and readability of massive spatial information resources and services.
