【摘要】 空间信息的集成和服务是当今研究的热点。数据的分布式、网络化特征以及应用需求的多元化使得单一数据集成模式很难满足用户的需求。结合应用需求、数据服务方式和Web服务技术,提出和建立了一种面向网络的空间数据多级集成模式,较好地实现了面向网络的空间数据集成。更多还原

【Abstract】 The Integration and service of spatial information is the research hot problem.The distributing,network characters and the multi-application demand make a single spatial data integration schema difficult to meet the requirement of the users.According to the application requirement,spatial data service mode and Web service technology,a network-oriented spatial data multi-level integration mode is put forward and set up.This mode includes data-level integration,platform-level integration,Service-level integration and application-level integration,which ascribes the spatial data integration problem to the corresponding multi-level mode integration problem and satisfies the application requirements.In this mode,spatial data access service is very important.A simple feature-based spatial data access and portray service flow is presented,and others can be extended according this model.In the end,a service-oriented spatial data integration system is carried out which realizes service and application level spatial data integration and service using WMS spatial data access service.This system validates the multi-level integration theory and technology.更多还原
