From: Machine-learning-based reconstruction of Ming-dynasty defensive corridors in Yuxian
a No visibility density scenario (noVIS); b No military settlement kernel density scenario (noKED); c No slope scenario (noSLOPE); d Corridor network based on 90 m DEM (DEM90). The background is the comprehensive defense cost surface, where warm colors indicate lower costs, and the blue lines represent the predicted defense corridors.
