地理格网互操作增强了地理格网信息资源的融合能力，促进了地理格网信息资源的充分合理利用。然而，地理格网互操作解决方案复杂，通用Web协议没有针对具体地理格网互操作的定义，需研究通用Web协议与地理格网互操作的藕合。OGC WCPS是比较好的地理格网互操作语言规范。本研究在剖析WCPS语言主要特点基础上，归纳了标准的地理格网及其互操作的函数模型，分析了地理格网互操作Web实现的相关协议与标准规范，创造性地提出WCPS与Web传输协议的地理格网互操作耦合模型，针对地理格网分析的Web实现展开快速原型研究，结果表明，WCPS与Web应用协议的耦合可有效提高地理格网分析的互操作性，增强GIS基础设施的服务功能，为WCS Processing扩展标准的制定与更新提供了科学判据，从而为国家区域数字化建设提供支持。

The explosion of available Geographic Grid resources in a wide range of Earth Science System appli-cation domains is shifting the paradigm of Earth Data Science. To exploit and acquire further insights and knowl-edge based on archived Geographic Grid resources, the existing infrastructures and techniques need to be scaled up and scaled out. However, adding more nodes does not provide a real analytics capability improvement if it is implemented without a corresponding analytics service interfaces among these nodes. The development of stan-dard-based online analytics services is considered as one of the potential solutions and is becoming indispensable to strengthen mutual integration between Geographic Grid information systems and other information systems. In this study, standard-based Geographic Grid models and analytics operations are reviewed and discussed by considering different web communication protocols, making it possible to explore different modular coupling and application profiling. Based on the probe of OGC Web Coverage Processing Language (WCPS) specifica-tions and relevant Web Coverage Service (WCS) 2.0 core and extension specifications, a web interoperability study is carried out to prototype an interoperable Geographical Grid analytics service. Accordingly, the research concludes the coupling patterns, principle issues and application directions for future explorations on Geographi-cal Grid Analytics web applications. The result shows that the coupling of WCPS and OGC WCS 2.0 can effec-tively improve the interoperability of Geographical Information Application Infrastructure in terms of Earth Sci-ence System monitoring and forecasting, so as to provide an effective support to National Digital Information In-frastructure Initiatives.
