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.
