随着空天地一体化地球观测的推进,对 GIS时空参考坐标系的Web解析应用服务的发展提出新需求.通过分析大数据背景下GIS数据服务对动态时空参考坐标系统Web标识与解析的需求,以时空互操作为切入点,提出动态坐标系解析模型及基于URL和地理标志语言的动态时空参考坐标系统Web标识与解析方法.基于开源组件设计服务原型展示,以增强地理信息服务互操作能力,其标准化应用可有效提供地理信息服务的时空一致性支持.%The advancement of the integration of earth and space observation brings new requirements on the application of Web interpretation services on GIS space time coordinate reference system(CRS).Based on the requirement analysis of the dynamic CRS Web identification and interpretation for GIS data services in Big data era, spatial-temporal interoperability was chosen as a starting point for the research to put forward the dynamic CRS interpretation model,Web identification and interpretation based on URL and Geography Markup Language(GML).A corresponding prototype application was customized based on open source components to demonstrate the solution as one of effective technologies for supporting consistent and interoperable GIS Web services.
