摘　　要：随着网络GIS应用需求的迅速增长,为海量空间数据建立高速的共享机制已经成为研究热点。提供了基于SOAP的海量空间数据服务方案,将空间数据服务分为两种应用类型,即使用GML用于数据量小的空间数据服务和FTP处理数据量大的空间数据服务。通过在AM/FM系统中应用实践及分析,使用这种方案不仅可以解决数据共享与集成,而且能够为目前的GIS应用提供功能完整、稳定可靠的数据服务。Methods to establish the sharing mechanism for spatial data have been the focus of active reseach over the past few years in GIS field as the increasing of spatial data resources and requirements for the GIS users. In this thesis we propose a method for large capacity spatial data based on SOAP, which is a realization of Web Service, through the analysis about OCG Spatial data services and GIS requirement for remote data services. Spatial data services are divided into two different service, one service processes little capacity data requirement using XML encoding and the other processed massive data requirement using FTP services. This solution can provide efficiency data service for spatial data sharing and integration through the implementing it in the AM/FM system.
