This API provides the boundary contours of port and airport domains owned by the Brittany region in France. It covers the ports of Lorient, Saint-Malo, and Brest, as well as the airports of Quimper, Dinard, Rennes, and Brest. The data is published via the Brittany regional open-data platform and is freely accessible without authentication. It can be used for mapping, spatial analysis, or planning purposes related to regional transport infrastructure managed by the Brittany region.Contour des domaines des ports (Lorient, Saint Malo, Brest) et aéroports (Quimper, Dinard, Rennes, Brest) appartenant à la région Bretagne
