An implementation of the method described by Pontius et al. (2011), which compares a reference map at time 1, a reference map at time 2 and a simulated map at time 2 to evaluate allocation performance at multiple resolutions while taking into account persistence. The method quantifies disagreement within coarse squares (minor allocation disagreement), disagreement between coarse squares (major allocation disagreement), disagreement about the quantity of land use change and agreement.

ThreeMapComparison(x, x1, y1,
factors, categories, labels, ...)
either a RasterLayer of observed land use at time 0 or an object
inheriting from class Model
a RasterLayer of observed land use at a subsequent time. Only
required if x is also a RasterLayer
a RasterLayer of simulated land use corresponding to x1. Only
required if x is also a RasterLayer
additional arguments to raster::aggregate
numeric vector of aggregation factors (equivalent to the 'fact'
argument to
raster::aggregate representing the resolutions at which
model performance should be tested
numeric value indicating the timestep of the simulated land use
map. Only required if x is a Model object
numeric vector of land use categories in observed maps. Only
required if x is a RasterLayer
character vector (optional) with labels corresponding to
categories. Only required if x is a RasterLayer
A ThreeMapComparison object.
