摘要
空间互操作已经成为地理信息共享领域研究的重要内容,广义的空间互操作也逐渐成为空间共享技术的代名词。虽着空间互操作研究的深入,空间互操作的模式与方法也逐步多样化起来。本文分别对基于语义空间数据互操作模式,开放式地理数据互操作规范与分布式异构数据库互操作框架,主流GIS平台互操作产品以及ISO/TC211的空间互操作服务体系结构进行分析的基础上,提出了改善各种互操作技术,以提升互操作性能的方法,指出了空间互操作技术框架的发展规律与趋势。从数据转换到开放文件格式,从标准交换格式到应用程序接口,从空间数据库到Web服务的集成,随着时间和互操作技术的发展,互操作的性能也在逐步提升。
In the research of sharing of geographic information, spatial interoperability has become a very important content of space sharing technology. Gradually, general spatial interoperability has become a pronoun of space sharing technology. As the research progressing, the modes and methods of spatial interoperability become diverse. On the basis of analyzing semantic spatial interoperability mode, open geographical data interoperability criterion and distributed isomerous database interoperability architecture, the mainstream GIS platform interoperability products, as well as ISO/TC211 spatial interoperability service architecture, this paper puts forward a new way to advance the capability of interoperability by improving various interoperability technology and proposes the regularities and trends of spatial interoperability architecture＇s development. From data transformation to open file format, from standard transformation format to application program interface, from spatial database to web service integration, as well as the rapid development of interoperability technology, the capability of interoperability has improved gradually.
