Figure 3

Dendrogram showing the relationships between the 20 landform classes generated by automatic classification within the LQ-8, LQ-11, and LQ-20 test areas. The gray rectangles denote the five major landform types identified manually by assigning geomorphologic interpretations to classes, while the multidimensional distance along the top of the dendrogram is the distance between classes in attribute space."
