dc.description.abstractThe primary aim of this research paper is to develop an easy-to-use tool package called Landslide Susceptibility Mapping Tool Pack (LSM Tool Pack) for producing landslide susceptibility maps based on integrating R with ArcMap Software. The proposed tool contains 5 main modules namely: (1) Data Preparation (DP), (2) Feature (Factor) Selection (FS), (3) Logistic Regression (LR), (4) Random Forest (RF) and (5) Performance Evaluation (PE). The FS module brings a novel approach to determine the best factor subset in the production of landslide susceptibility maps. The feature ranking values of factors were calculated by several feature ranging methods (i. e. chi-square, information gain, rank correlation, and random forest feature importance). The logistic regression method was used at the model prediction stage for each feature ranking and different models were produced for each ranking result. And, in the last step of the FS analysis, tests of statistical significance (i.e. Wilcoxon signedrank test, F- Test, Kolmogorov Smirnov test, and One-Sample t-test) were used to determine the significance of the difference between models. As a result, the best factor sets determined by the FS module were used as input factors in the LR Module and the RF Module to produce LSMs. Also, users can calculate the performance metric of landslide susceptibility maps by several performance metrics (overall accuracy, Area under the ROC Curve (AUC) value, kappa, Fl score, and more) with additional integrated the PE Module in ArcMap Software. The LSM Tool Pack is applied to the Sinop province of the Black Sea region of Turkey. Considered the FS module, Case 1 was selected as the experimental dataset for this present study. In the selected Case 1, feature ranking method and statistically significant analysis were determined by Chi-square and F-Test, respectively. As a result, Model-12, which is contained 12 landslide causative factors, was determined as the optimum subset. According to the results obtained by the accuracy assessment process, the RF model showed the best prediction performance with an AUC value of 0.8898. On the other hand, the calculated AUC value was 0.8119 for the LR model. The experimental results (using with dataset in actual study area) confirm the ability of the proposed feature selection approach in the landslide susceptibility mapping process.en_US
