Abstract
Abstract This study investigates the effects of hybrid modeling approaches factor standardization and categorical mapping on the performance of landslide susceptibility maps. For this purpose three models of frequency ratio (FR) weights of evidence (WoE) and certainty factor (CF) and six hybrid models based on the combination of FR WoE and CF with logistic regression (LR) and analytical hierarchy process (AHP) were used to analyze landslide susceptibility in Van Turkey. Eleven factors including elevation slope aspect profile curvature plan curvature lithology land use/cover normalized difference vegetation index topographic wetness index terrain ruggedness index distance to faults and distance to roads were used. The analysis results were categorized into five groups as Very High High Medium Low and Very Low landslide susceptibility using four classification methods of equal interval natural breaks geometric interval and quantile; thus 36 landslide susceptibility maps were obtained. We compared the accuracy of the maps using area under the curve for success and prediction rates percentage distribution of landslides and landslide density index. The results indicated that 26 out of 36 maps had good prediction accuracy but differed in predictive abilities. Furthermore the comparisons revealed hybrid modeling improved prediction performance and the AHP-based hybrid models gave better results than the LR-based hybrid models. The CF for factor standardization and the geometric inte
