中文摘要：

随着网络环境下空间信息服务数量和种类的不断增多,空间数据的使用和转换日趋频繁,空间数据产品的可信度成为困扰用户科学地使用空间数据产品的难题。空间数据起源记录了空间数据产品的衍生过程,是数据可信度评估的重要参考因素,对空间数据产品的维护与更新、空间信息处理工作流的检测和优化等有着重要意义,有助于提升空间信息服务应用的水平。该文介绍了空间数据起源的概念,分析了当前国内外在该领域的研究进展,针对空间数据起源的采集、管理和服务等问题,提出了基于面向服务体系架构SOA的空间数据起源系统原型框架,为分布式环境下空间数据起源系统化的管理和研究奠定了基础。

英文摘要：

As the number and types of Web services grows,the usage and transformation of geospatial data become more and more frequent.The quality and reliability of geospatial data products becomes challenge issues towards scientific usage of these data products.Geospatial data provenance,the derivation history of geospatial data products,provides a context for evaluating the quality and reliability of data products,updating and maintaining data products,and checking and optimizing geoprocessing workflows,thus promoting the applications of geospatial information services.In this paper,the concept of geospatial data provenance is given.Related work on geospatial data provenance is introduced.Finally,a prototype framework for SOA-based geospatial data provenance is proposed,which can support provenance recording,storage,and query in a distributed environment.
