For the next steps on the data see [[Jeemin Sim (Work Log)]]. This includes details of how to load the TIF data.
===Approach===
We want to choose some layers to work with. https://en.wikipedia.org/wiki/Hierarchical_clustering notes that "One can always decide to stop clustering when there is a sufficiently small number of clusters '''(number criterion)'''. Some linkages may also guarantee that agglomeration occurs at a greater distance between clusters than the previous agglomeration, and then one can stop clustering when the clusters are too far apart to be merged '''(distance criterion)'''."
In a similar vein, https://en.wikipedia.org/wiki/Determining_the_number_of_clusters_in_a_data_set describes the elbow method, using AIC/BIC, etc., as well as an Information theoretic approach, the silhoette method, etc.
For us:
1) 80% of points in hulls
2) Elbow on fraction of maximum hull area in hulls
3) Chosen by the researcher
3) Maximum R-Squared
===First Estimation(s)===
