“一张图”框架下的城市应急疏散数据融合

Urban emergency evacuation data fusion under framework of “One Map”

为实现不同数学基础、不同数据模型、不同分类分级城市应急疏散数据的综合利用,提出了"一张图"框架下的多源空间数据融合策略,设计了多源空间数据融合框架.研究结果表明:在城市应急疏散"一张图"框架下,城市应急疏散决策的效率和水平得到了显著提高."一张图"框架对城市应急疏散数据融合研究具有一定的参考价值.

In order to make use of urban emergency evacuation data that has different mathematics foundation, different data model, different classification and grading comprehensively, this study brought forward the fusion strategy of multisource spatial data based on ＂one map＂, and designed the frame of multisource spatial data fusion. The experiment indicates that the efficiency and level of urban emergency evacuation decision-making advances remarkably supported by the ＇,＇one map＂ framework of urban emergency evacuation. The framework of＇,one map＂ is valuable for urban emergency evacuation fusion research.
