Unsupervised Image Classification


The top image is the reclassified (unsupervised) image. The bottom image is the original. The image was reclassified into 15 classes. These classes were then recoded into similar and more general class types (i.e. all water, agriculture etc......). Appropriate colors were then assigned to each land use type.
I encountered issues post reclassification with some land class distinctions....mainly cleared land, and crop land. These issues could have been addressed, but were beyond the scope of this lab.
