超大正射影像数据互联网发布系统的设计与实现

System design and implementation of mass DOM data Internet release

正射影像(DOM)数据在WebGIS中应用要解决的首要问题是如何将具有超大范围的海量正射影像数据在互联网进行有效发布。本文在进行了理论研究并做出了大量实践工作的基础上,围绕超大影像数据的互联网有效发布问题,展开深入分析和讨论,最终给出了基于MVC的三层体系结构系统的设计与实现。

The first thing to do is how to distribute the mass DOM data effectively, especially on Internet. According to the distribution teehniques on mass DOM on stand-alone pattern and of other spatial data on Intranet pattern, this paper discusses the scheme and techniques of mass DOM distribution on Internet. On the other hand, for effective distribution of mass geography information data, this paper discusses the schema on different Internet architecture and some problems of the implementation. Finally, we present and validate the instance of this system.
