面向服务架构下主动地理信息服务模型研究

通过引入服务的主动发现、定制、加载与使用机制,支持新服务、新应用的按需创建,为用户发现、定制和运行能够满足用户需求的服务,从而改变当前用户只能被动地使用现有服务的应用模式,以应对信息化需求的不断发展和变化。主动型的地理信息服务在Web服务框架模型、基础协议的基础之上,增加识别用户需求和处理的能力,使用户能够根据特定需要选择合适的服务,使服务能够自动适应用户的需求。本文讨论了面向服务架构下的主动地理信息服务模型,该模型以Web服务技术为支撑,以扩展的UDDI等协议为规范,并对该模型进行测试,实验证明该模型可以有效地主动式的地理信息服务。

Research on active military geography information service model upon on service oriented

This paper provides the service for user to discover,customize and run through introducing the active discovering mechanism,active customizing mechanism and active loading mechanism.This will support the designing according to need of the new services and new applications.And will change the model that the current users use only the existing services passively and satisfy the incessant mutative need of information war.The active military geography information services add the capability identifying the need based on the Web Service framework model and protocol.The will make users select services according to the specifically need.Finally,this paper test the model,and the result indicates that the model can provide the active GIS service.
