中文摘要: 地理分析模型的共享与集成是解决复杂地理问题的重要途径,是GIS、虚拟地理环境发展的关键。然而,模型的异构性导致大量模型散布于网络空间,缺乏有效的共享和重用方法。本项目针对地理分析模型数据格式、交互操作、运行环境的异构性展开服务化封装研究。(1)研究计算机自动处理和人工辅助相结合的模型数据格式获取方法,以及基于DFML的数据格式描述方法,实现对地理分析模型输入输出数据格式的快速获取与统一描述;(2)研究基于流程配置的地理分析模型封装模式,构建模型执行引擎,实现用户可广泛参与的自主式模型封装;(3)研究地理分析模型的智能托管与服务映射机制,构建通用的、可动态扩展的模型运行环境,以及模型服务的宿主环境。形成普适的地理分析模型的服务化封装方法与工具,提高模型封装的自动化程度。研究成果可为地理分析模型的网络共享与集成提供新的思路与方法,对提升GIS的地理分析能力,拓展地理信息服务具有重要意义。

英文摘要: The sharing and integration of geographic analysis model play significant roles in tackling complex geographic problems, and also are critical issues for the development of GIS and virtual geographic environment. However, the heteroigeneity characteristics of geographic analysis model result in the predicament that vast models distributing in cyberspace and the lack of effective ways for model sharing and reusing. This project focuses on the study of service encapsulation in respect to the heteroigeneity of data format, interactive operation and runtime environment of geographic analysis model. The specific steps include, a) study the extraction method of model data format that integrates automatic computer processing and human assisting, and explore DFML-based description method for the purpose of effective extraction and uniform description of the input/output data format of geographic analysis model; b) research encapsulation modes of geographic analysis model based on workflow configuration, and build model execution engine so as to provide function of autonomous encapsulation alllowing broad participation of users; c) study the mechanism of intelligent management and service mapping of geographic analysis model, and construct host environment of model service as well as all-purpose and dynamically ext
