New results, using the seasonal feature of polygon area per quadrant

Typology based on MOD12Q1 (Water, Evergreen Broadleaf forest, Deciduous Broadleaf forest, Open shrublands, Woody savannas, Croplands)

Typology (Single crop, Double crop, other classes)

Using a combination of features (Basic + Polar), 90% of correct classified points (2074 instances).

Results presented in paper

Basic features X Polar Features. Typology (Single crop, Double crop, other classes)

TerraClass (2008) X GeoDMA (growing season 2007-2008)
