A pair of before-and-after digital aerial photographs with 50\u2009cm spatial resolution was used to detect landslide occurrences in Yongin area, Korea. Iterative random sampling was run ten times in total and each time it was applied to the training and validation datasets. Thirteen landslide causative factors were derived from the topographic, soil, forest, and geological maps. The FR scores were calculated from the causative factors and training occurrences repeatedly ten times. The ten landslide susceptibility maps were obtained from the integration of causative factors that assigned FR scores. The landslide susceptibility maps were validated by using each validation dataset. The FR method achieved susceptibility accuracies from 89.48% to 93.21%. And the landslide susceptibility accuracy of the FR method is higher than 89%. Moreover, the ten times iterative FR modeling may contribute to a better understanding of a regularized relationship between the causative factors and landslide susceptibility. This makes it possible to incorporate knowledge-driven considerations of the causative factors into the landslide susceptibility analysis and also be extensively used to other areas.<\/jats:p>","DOI":"10.1155\/2017\/3730913","type":"journal-article","created":{"date-parts":[[2017,9,6]],"date-time":"2017-09-06T17:54:06Z","timestamp":1504720446000},"page":"1-21","source":"Crossref","is-referenced-by-count":61,"title":["Landslide
