地理空间知识服务概论

Geospatial Knowledge Service:A Review

  • 摘要: 目的 随着互联网的广泛应用,地理信息技术已经从地理信息系统向地理信息服务转变。人们不仅希望从网络上获取地理空间数据和信息,同时也希望在网络上获取地理空间知识。地理空间知识网络服务以互联网为平台,将已有的地学常识、规则、模型、过程等各种地学知识在网上进行注册,对各种用户提供共享服务。首先阐述了地理空间信息服务向地理空间知识服务转变的背景,在此基础上介绍了地理空间知识和地理空间知识服务的基本概念,以及地理空间知识服务所需要的技术及其实现的基本步骤。

     

    Abstract: Objective Geographic information technology is evolving from a Geographic Information System to aGeographic Information Service,given the increasingly widespread use of the Internet.Not only aregeospatial data and information shared online,but also geospatial knowledge is disseminated via theInternet.Geosciences'rules,models,and processes can be registered to the web,and provided to va-rious users through geospatial knowledge web services based on the Internet.In this paper,the back-ground for this transition from geospatial information to geospatial knowledge services is introduced,and key concepts of geospatial knowledge,geospatial knowledge services and the technologies are e-laborated.Finally based on this foundation,an implementation of a geospatial knowledge services isdiscussed.
