Note
This chapter shows how to create an oversimplified model to predict the probability of landslides.
First, we calculate slope (choose among various backends; the interested reader can calculate the difference between the outputs):
Then we create a model of predicted rainfall, based on the interpolation of rainfall values at meteo stations:
The probability of a landslide will be very roughly related to both rainfall and slope (of course a real model will use more layers, and appropriate parameters), let’s say (rainfall * slope )/100:
