Taking the Yishui County, Shandong Province as the research area, we processed GF-2 images from different periods in May 2018 and May 2020. Based on their spectral and texture differences, combined with topographic and geomorphic features, multiple hidden geological hazard points are identified. Finally, we conducted on-site investigations and ultimately identified multiple potential geological hazards.
