UAV survey for documentation and conservation of Han City in the UNESCO mixed heritage site of Mount Wuyi, China.

Chengcun Han City is an important part of the UNESCO Mixed Heritage Site of Mount Wuyi, China. To tackle the problems caused by the size and location of the site, the current study thus aims to explore the feasibility of combining digital survey methods with tilt photography and remote sensing technology. The orthophotos lead to the creation of an ABIM (Archaeological Building Information Model). The value hierarchy established based on social network analysis provides new ideas for archaeological surveying and constructing an unmanned remote sensing monitoring system for large sites.
