Operating Characteristic curves to validate models of deforestation in the
Ipswich watershed between 1985 and 1991 using three suitability maps based
on: random location (bottom ROC = 50%), logistic regression with protected
areas (middle ROC = 65%), and multi-criteria evaluation with a spatial
filter and protected areas (upper ROC = 70%).
