FIGURE 7.8. LAND COVER CLASSIFICATION MAPS COMPUTED USING THREE TYPES OF
TRAINING SETS AND 11 LANDSAT AND MAP-DERIVED VARIABLES. Each display emphasizes
the area of shifting cultivation in black. All 3 classifications were computed using stepwise linear dis-
criminant analysis with apriori probabilities of land cover occurrence. The 11 variables were the 4
LANDSAT MSS bands, the 4 physiographic variables and the 3 cultural features variables.
