地理信息公共服务平台的用户分类及服务分类

地理信息技术的发展经历了集中式、模块化、组件化的过程,目前正向地理信息的Web服务方向发展。传统的集中式地理信息系统中,功能的分类决定了用户的分类;而在地理信息服务的架构中,用户的分类导致服务的分类及其与用户分类的映射。本文从地理信息服务的架构出发,分析并提出了面向服务的地理信息公共服务的用户群分类与对应的服务分类,为地理信息公共服务平台的构建和地理信息服务资源的有效组织和整合提供理论依据。

Categorization of Users and Services in Geographic Information Public Service Platform

Geospatial technologies are evolving from centralized Geospatial Information System to web-based Geospatial Information Service.In traditional Geospatial Information System,the classification and aggregation of functions imply the categorization of end users.However,in distributed Geospatial Information Service,the categorization of end users determines the classification of services and their mapping to the user＇s groups.Based on service oriented architecture,this paper analyzes and proposes a service-oriented categorization of user＇s groups and its correspondent aggregation of services in Geospatial Information Service platform.This categorization and aggregation provides a theoretical foundation for designing Geospatial Information Service Platform and efficient organization and integration of geospatial information service resources.
