摘要
遥感影像数据的共享是发展的必然趋势。遥感影像发布系统的研究与建立是当前的一个热点问题。本文介绍了MapServer的特征,阐述了基于MapServer建立遥感影像发布系统的原理和特点及遥感影像数据的组织。讨论了发布界面Ka-map引入的Ajax技术和缓存的设置。给出了利用MapServer等一系列开源软件实现遥感影像网络发布的框架。
Data sharing is an inexorable trend as the development of remote sensing application develops. The remote sensing image publishing system, which is a key element in data sharing, has been a hot topic worldwide. This paper expounds the theory and characteristics of the image publishing system, and it describes remote sensing data structure as well. It also discusses Ajax and cache setting technique in Ka-map and presents a system framework based on MapServer and other open source software.
