Geospatial Technology System and Full-cycle Applications in Smart City Emergency Management
摘要
Abstract
With the deepening development of smart cities,urban emergency management is shifting from post-disaster response to a full-cycle management paradigm encompassing pre-disaster prevention,in-disaster response,and post-disaster recovery.Geospatial technology,with advan-tages in spatial information acquisition,multi-source data fusion,and spatio-temporal correlation analysis,has become a fundamental support for smart city emergency management.In this paper,we reviewed the geospatial technology system for smart city emergency management,and discussed key components,including multi-source spatio-temporal data acquisition and risk basemap construction,heterogeneous data fusion and spatio-temporal correlation analysis,disaster process simulation,and urban spatial representation.Then,we further summarized the application logic of this technology system across the full emergency management cycle,including pre-disaster risk identification and early warning,in-disaster dynamic sensing and coordinated response,and post-disaster damage assessment and recovery monitoring.Finally,in response to challenges such as difficulties in multi-source heterogeneous data integration and the lagging dynamic update of high-precision digital basemaps,we proposed future development directions,including the construction of a space-air-ground integrated sensing network,the enhancement of intelligent analy-sis and simulation capabilities,and the development of a computable urban digital base.关键词
