摘要
格网技术作为新一代的Web技术,必将深刻影响GIS的发展。格网计算为数据密集型空间分析提供了资源支持。数据格网为海量空间数据分布式存储、管理、传输、分析提供了一体化的解决方法。格网技术为VRGIS实时场景渲染和海量场景数据存储以及GIS互操作问题的解决提供了一种新思路。格网中的智能体组件动态组装应用软件将对GIS应用开发方式产生重大影响。通过建立空间信息格网可以实现中国GIS产业的跨越式发展。
Grid technology will influence the development of GIS deeply,especially on web-based large-scale GIS.Grid computing technology provides the powerful computing resource support for the data-intensive spatial analysis.The data grid offers an integrated solution for storage,management,transmission,analysis of large-scale spatial data and a new method for real-time scene rending and storage of large-scale scene data in VRGIS.The interoperability problem will be solved more easily by grid technology.The software development model by agent components that quarter at grid node to build up application software in large-scale GIS domain will influence the way of GIS application software development deeply.
