Description: Rockfall source areas were mapped using a logistic regression model based on the following predictor variables: topography bedding intersection angle, plan and profile curvature, aspect, elevation, slope, topographic position, and color. The source areas were then used as inputs in the Gravitational Process Path Model (GPP) to model the rockfall process area from source to runout. The values in the output raster represent the number of times rockfall material passed through each cell during the rockfall process event (the transition frequency).
