Sources and method
- Outlines
- Natural Earth, 1:10m Admin 1 - States, Provinces, public domain. The outline of Brittany is the departments Natural Earth draws there, joined along their shared borders.
- Boundary
- De facto, as drawn by Natural Earth. A region is drawn whole, every island included; a country is its main territory.
- Area
- Measured on the WGS84 ellipsoid from the full-detail outlines, shown rounded.
- Drawing
- Each outline is projected with an equal-area projection centred on its own centroid, so areas stay true and the two can be laid over each other.
