Abstract：Earthquake disasters exhibit characteristics of instantaneous occurrence,chain reactions,and wide spatial coverage,frequently resulting in"information silos"in the disaster area,which severely hinders emer-gency response decision-making.Rapid and accurate acquisition of post-disaster geographic information is crucial for supporting efficient response efforts.Traditional earth observation methods are difficult to meet the demands for fine evaluation within the critical"golden 72 hours"after the earthquake in terms of timeliness and resolution.Un-manned aerial vehicle(UAV)low-altitude remote sensing mapping technology has become an indispensable techni-cal system for emergency response due to its advantages of high mobility,high timeliness,low cost and high reso-lution.However,the data limitations from single sensor,the problem of route planning in complex disaster scenar-ios,and the post-processing pressure caused by"data explosion"are still the core challenges faced by current UAV emergency mapping.This paper focused on this,and proposed a fast acquisition and processing method of emergency geographic information that integrates multi-source information,aiming to provide more reliable geospa-tial data support for earthquake emergency command.
