摘要
定位技术的大众化和数据应用的广泛化正让传统大地测量模式悄然改变。本文从分析大地测量信息系统计算模式的发展过程入手,提出了网络环境下大地测量信息服务的总体框架,重点分析了以定位服务、控制点服务和数据服务为核心的服务内容,并对构建服务所要应用的XML、数据标准和元数据三个关键技术进行阐述,最后还对基于框架的大地测量过程进行了研究,实现了基于Web服务技术的大地测量生产和服务,为实现大范围跨系统的大地测量信息集成应用提供就新的技术思路。
Popularization positioning technique and widely application are changing traditional geodetic producing and application model. Started by the development of geodetic information system computing model, Geodetic Web Services Framework （GWSF） is brought out and its main services （e. g. positioning service, control point service and data service） are expatiated. Extensible markup language, data standard and metadata as three key technologies of GWSF are discussed followed. As an example, mobile navigation service in CORS is introduced to explain how to use GWSF. Supported by GWSF, geodetic activities can be loosely coupled in virtual dynamic web services. It makes geodetic multi-system and multi-source data integrated application possible.
