摘要
随着遥感技术、解析和数字摄影测量技术的发展,空间数据的数量以惊人速度增长,并具有数据结构复杂、多类型、多投影方式、多来源等特点,给用户综合多种空间数据、获取自己所需的地图带来极大地困难。采用一种基于Web、遵守OGC标准且以开源软件为开发基础的地图服务器的设计方法,可实现融合多格式、多来源的空间数据,为用户提供地图服务。
With the development of remote sensing technology, analytical and digital photogrammetry technology, the quantity of the spatial data increases with astonishing speed. The spatial data has complex data structure, various formats, projections and sources, etc. The huge difficulty is brought to the customer who synthesizes various spatial data and obtains a map he or she needs. A method, which is based on web, conforming to the OGC standard and making use of some open source softwares, to develop a new map server, the spatial data is blended with kinds of formats and various sources, and map services are provided for the users.
