5 symbolization classes based first on the Natural Breaks (Jenks) and then the Equal Interval classification method.
Projection:
Equidistant Conic
Map analysis:
Perimeter length was calculated using the "calculate geometry" tool in ArcMap. The results should be considered a rough measure rather than an authoritative quantification.
One of the important takeaways from these maps is that a coastal location was nearly as important as actual area in determining perimeter length. The complex geometries of coastal provinces figure in many of the mappings in this project.
