Sharing and integrating Remote Sensing (RS) and Geographic Information System/Science (GIS) models are critical for developing practical application systems. Facilitating model sharing and model integration is a problem for model publishers and model users, respectively. To address this problem, a framework based on a Web service for sharing and integrating RS and GIS models is proposed in this paper. The fundamental idea of the framework is to publish heterogeneous RS and GIS models into standard Web services for sharing and interoperation and then to integrate the RS and GIS models using Web services. For the former, a "black box" and a visual method are employed to facilitate the publishing of the models as Web services. For the latter, model integration based on the geospatial workflow and semantic supported marching method is introduced. Under this framework, model sharing and integration is applied for developing the Pearl River Delta water environment monitoring system. The results show that the framework can facilitate model sharing and model integration for model publishers and model users.
共享和集成遥感（RS）与地理信息系统/科学（GIS）模型对于开发实际应用系统至关重要。促进模型共享和模型集成分别是模型发布者和模型用户面临的问题。为解决此问题，本文提出了一个基于Web服务的用于共享和集成RS与GIS模型的框架。该框架的基本思想是将异构的RS和GIS模型发布为标准Web服务以进行共享和互操作，然后使用Web服务集成RS和GIS模型。对于前者，采用“黑箱”和可视化方法来促进模型作为Web服务的发布。对于后者，引入了基于地理空间工作流和语义支持的行进方法的模型集成。在此框架下，模型共享和集成被应用于开发珠江三角洲水环境监测系统。结果表明，该框架可以为模型发布者和模型用户促进模型共享和模型集成。
