ABSTRACT

This paper proposed a geoscience model service integrated workflow-based rainstorm waterlogging analysis method to overcome the defects of conventional waterlogging analysis systems. In this research, we studied a general OGC WPS service invoking strategy, an automatic asynchronous invoking mechanism of WPS services in the BPEL workflow, and a distributed waterlogging analysis services integrated workflow to realize the reconstruction of a waterlogging analysis model based on the proposed method. The proposed method can make use of the flexible adjustment capability of the workflow and not only overcomes the inherent defects of conventional geoscience analysis methods but also realizes the integration and calculation of distributed geospatial data, models and computing resources automatically. The method has better construction convenience, execution reliability, extensibility and intelligence potential than a conventional method and has important value for dealing with more natural disasters and environmental challenges.

摘要

本文提出了一种基于地学模型服务集成工作流的暴雨内涝分析方法，以克服传统内涝分析系统的缺陷。在本研究中，我们研究了通用的OGC WPS服务调用策略、BPEL工作流中WPS服务的自动异步调用机制以及分布式涝渍分析服务集成工作流，以实现基于所提方法的涝渍分析模型的重构。该方法可以利用工作流的灵活调整能力，不仅克服了传统地学分析方法的固有缺陷，而且实现了分布式地理空间数据、模型和计算资源的自动集成和计算。该方法具有较好的施工方便性，
