The first classification, realised with this SPOT image (image of the Var region in France), doesn't succeed in separating the different Alep pines planting density sub-classes.
The extraction and the processing of the pines mask succeed in separate the different pines planting density.
This post-classification has been re-introduced in the first classification. We can see that the planting density sub-classes disposition follow a circular scheme. The high density forests are in the middle and the low density forests are in the periphery.
