“Cartographers at National Geographic discuss how they select an appropriate map projection for the September 2012 magazine map supplement. –World maps usually center on the land, with the Pacific Ocean divided as bookends. To show each ocean as a whole with the least distortion for our ‘Beneath the Oceans’ supplement map, we used a map projection called an interrupted Mollweide centered on the Pacific.”
