DESCRIPTION
Module r.futures.validation allows to validate land change simulation results. It computes:
- Allocation disagreement (total and per class), see Pontius et al, 2011
- Quantity disagreement (total and per class), see Pontius et al, 2011
- Cohen's Kappa
- Kappa simulation, see van Vliet et al, 2011
This module can be used for any number of classes. Input raster original represents the initial conditions and is needed only for Kappa simulation.
EXAMPLES
Validate land change simulation output by computing quantity and allocation disagreement.
r.reclass input=simulated_2016 output=simulated_2016_reclass rules=rules.txt
r.futures.validation simulated=simulated_2016_reclass reference=reference_2016 original=orig_2001
