摘　　要：针对地图服务不能满足按需计算的若干不足,为有效利用已有网络资源,文章基于服务协同技术思想分析并设计了地理制图服务的概念。通过对地理制图服务原理、技术特点等关键技术的分析,参考以OGC WMS为代表的地图发布技术,文章提出了对WMS接口进行功能扩展与Web Service封装构建地理制图服务的思路,并采用Microsoft.NET2.0与ArcServer具体实现了服务。文章通过移动点自动追踪应用验证了制图服务的自定义与实时制图功能,讨论了服务协同计算思想在地理计算中的潜在价值。For the drawbacks that traditional cartography service could not compute on demand, in order to take efficient use of current network sources, in this paper, the geography cartography service （GCS） concept was analyzed and designed, based on the service cooperative technique. By the analysis of the principle and working mechanism of customized web mapping, with map publishing technology of OGC WMS as references, extension of WMS interface function and geography cartography service （GCS） with a service-oriented web mapping component were proposed and realized by adopting Micorsoft.NET2.0 and ArcServer. The self-definition and function of real-time cartography service were verified by moving tracing and the potential value of service cooperative computing in geocomputation was discussed.
