Exercise 7: Risk Model for Landslide Susceptibility in Oregon

Goal: The goal for this exercise was to use python to generate a risk model regarding landslides in NW Oregon.




Methods: This exercise used data from our previous exercises and went further in order to create a risk model to be used in predicting landslides. Numerous tools were used including the creation of a fishnet, buffer, intersects, reclassifying of rasters, zonal statistics and also various raster tools to extrapolate a risk raster.

Results: The code and resulting map for this exercise can be found below - Code (Figure 1) Map (Figure 2.) This map shows areas in NW Oregon with varying levels of risk concerning landslides. This can be valuable when selecting locations to live, insurance purposes, disaster preparedness, etc.
