4.2.2 Zoning

Fig. 4.13 Zoning widget

Convert your models into landslide susceptibility maps.

4.2.2.1 Usage

1. Pick the input model with a dialog (1)

2. Pick the output map location. You can either type in the absolute file path yourself

   or pick one with a dialog (2).

3. Define the landslide susceptibility zones (2 Alternatives):

   1. Set default table (3)

   2. Define the zone boundaries yourself:

      1. Add (5) and delete (6) zones as needed

      2. Name the zones in the reclass table (11)

      3. Set the “Targeted landslide area in zone %” for each zone except the last

4. Update the graphs (4)

5. Apply (10)

The model info (7) shows an embedded version of the Model Info Widget

Zoning preview (8) and the ROC curve (9) offer a sneak peek at the resulting map.

If you started Zoning from the Model Builder Widget the selected Model will be available to you right away.

4.2.2.2 Information

The True Positive Rate (TPR) (y axis in (9)) corresponds roughly to the cumulative landslide area. The False Positive Rate (FPR) (x axis in (9)) corresponds approximately to the total area without landslides.
