应急地理信息集成建模框架技术研究

为了实现快速地分析处理应急测绘地理信息数据,往往需要对不同模型进行集成建模,提出了面向应急测绘的空间集成建模框架,并对其关键技术展开研究。该框架基于案例驱动进行空间集成建模,以服务链形式自动化分析处理应急测绘数据。此外,还提供应急测绘模型耦合校验方法,保证组合方案的可执行性和稳定性。最后以济南市化工厂危化品泄露应急分析原型系统为例,在可计算应急测绘案例库的驱动下,面向应急测绘的空间集成建模框架可以高效地进行应急空间信息服务组合。提出了基于案例驱动的空间信息服务组合方法,实现了组合方案的快速构建。

Research on Space Integrated Modeling Framework for Emergency Geographic Information

In order to analyze and deal with emergency geographic information data quickly and timely,we often need to integrate different models.Therefore,a spatial integrated modeling framework for emergency mapping is proposed,and its key technologies are studied.The framework is based on case driven Space Integration Modeling and automated analysis and processing of emergency surveying data in the form of service chain.In addition,the coupling verification method of emergency mapping model is also provided to ensure the executability and stability of the combination scheme.Finally,taking the emergency analysis prototype system of hazardous chemicals leakage in Ji'nan chemical plant as an example,it is proved that under the driving of the computable emergency surveying and mapping case database,the spatial integrated modeling framework for emergency mapping is highly effective for emergency spatial information service composition.A case driven spatial information service combination method is proposed,which realizes the rapid construction of the combination scheme.
