摘要
Abstract
To improve the update efficiency of 1∶10 000 digital line graph(DLG)in rapidly urbanizing areas,we proposed a collaborative up-date mode integrating multi-source data and multiple technical approaches.Taking Wuhan City,Hubei Province,China as a case,we developed a systematic update workflow incorporating regional classification and multi-technology integration by dividing the update area into regions with different update priorities and contents,and combining aerial photogrammetry,large-scale data generalization,high-resolution satellite image ac-quisition,and geographical conditions monitoring results.The results demonstrate that this approach completed the citywide update task within eight months,achieving approximately 70%higher efficiency compared to the previous cycle,and significantly reducing production costs while ensuring data currency and accuracy.The research outcomes provide replicable technical pathways and practical references for efficient large-scale topographic map update in similar regions.关键词
