中文摘要：

地理信息网络服务越来越普遍,但矢量数据服务在实际应用中却存在很多问题。针对现有的矢量数据服务接口标准（如WFS）过于简单无法满足复杂的实际应用的现状,设计了一个基于WCF数据契约的空间矢量数据服务模型。针对传统Web Service技术对大数据流处理效率低的问题,提出利用WCF信道压缩编码器提高大数据量传输的方法;同时利用WCF内置的安全模式实现了矢量数据的传输安全。

英文摘要：

Geo-information network service has become more and more popular,however the practical application of vector data service has lots of problems.Existing vector data service interface standard（such as WFS） is too simple,which doesn＇t meet the complex practical application.In allusion to the situation,a spatial vector data service model was designed based on WCF data contract.Considering the low efficiency of processing large data stream by traditional technology of web service,a method based on WCF channel compressed encoder was proposed.At the same time,the security of vector data transmission was guaranteed based on internal security mode of WCF.
