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.
Validate land change simulation output by computing quantity and allocation disagreement.
