Analog table #1

Open gghill opened 1 year ago

gghill commented 1 year ago

Construct an analog table with rows as EEZs, columns as species (or species groups) and cells as average sigma dissimilarity or a proportion of cells within that EEZ above a dissim threshold.

EXAMPLE: Finfish Crustaceans Algae Echinoderms
France 4.8 3.6 2.2 2.8
Norway 2.1 2.6 1.5 2.0
Scotland 2.9 3.0 2.1 2.2

Currently implemented in one form per species with proportion of analogs moving from one area to another (rows = origin, columns = destination):

EXAMPLE France Norway Scotland
France .84 .15 .22
Norway .17 .71 .12
Scotland .21 .18 .69

Subsequently visualized as a Sankey network and chord diagram (Gadus morhua, ssp119):

Progressing to further restrict this to analogs with source pixel dissimilarity > 2 and destinations inheriting at least 2 analogs (this removes a lot of the very thin threads in unlikely locations).
