The “compare” command

This command is used to compare two susceptibility raster layers by calculating the percentage area within each susceptibility class and generating a raster layer of the difference between the two input layers.

For help on the inputs of this command, run the following:

PyLandslide compare --help

This results in the following, including three inputs:

Usage: PyLandslide compare [OPTIONS]

    Compare two landslide hazard raster file.

Options:
    -f, --file-name TEXT  JSON file containing the sensitivity config.
    -l1, --layer1 TEXT    First landslide hazard raster file.
    -l2, --layer2 TEXT    Second landslide hazard raster file.
    --help                Show this message and exit.

To use the compare command, run the following and make sure to replace the inputs based on your case:

PyLandslide compare -f json_file.json -l1 layer1.tif -l2 layer2.tif

Further details on the structure and inputs to the JSON file are in the Tutorials Section.
