Abstract: To meet the demand for efficient handling of urban emergency incidents,this paper explores the construction of an emergency rapid mapping system to realize the application of efficient emergency mapping technology.By analyzing the application scenarios of emergency maps,this paper deconstructs their core characteristics and sorts out the map resource database system.On this basis,it designs the technical process of emergency rapid mapping and elaborates on key links in the process,such as data construction,map matching,and rapid output.Combining with the practical case of Ningbo,this paper introduces in depth the on-site construction and application of this mapping system.Practice shows that the emergency rapid mapping process constructed by this technical system has played a key supporting role in actual emergency handling and significantly improved the efficiency of emergency response and decision-making.

Key words: emergency scenario, map resource database, multi-scale database, map layout configuration, emergency rapid mapping
