The 100 m annual local climate zone datasets in Chinese big cities from 2000 to 2022

We employed a time-series mapping framework for urban morphology, producing dynamic mappings of urban morphology with a spatial resolution of 100 meters spanning from 2000 to 2022 in major Chinese cities, based on the local climate zone (LCZ) scheme. The results demonstrate strong inter-year consistency, and the accuracy of urban morphology change mapping is overall higher than 70%. Our dataset is divided into 6 parts according to geographical districts, each containing annual LCZ mapping of each province in the region. This dataset holds significant potential for enhancing urban morphology monitoring and advancing urban climate research.
