We reconstructed the walled cities of China that extend from the 15th century to 19th century based on multiple historical documents. By restoring the extent of the city walls, it is helpful to explore the urban area in this period. The correlation and integration of the lifetime and the spatial data led to the creation of the China City Wall Areas Dataset (CCWAD). Based on the proximity to the time of most of the city walls, we produce the China Urban Extent Dataset (CUED) from CCWAD.
