Coastline across the ocean, from where you’re standing

A couple of years ago, Eric Odenheimer wondered: If you stand on the beach looking out to the ocean and traveled straight until you reach land, what country would you reach? He only used latitude though. However, in real life, coastline is jagged and points in all directions, so you don’t always face east and west. Cartographer Andy Woodruff took these directions into account and drew a more accurate picture.

For each continent, Woodruff drew a map that shows coastal points around the world that point directly to that continent. For example, the above shows everywhere that points directly at Australia and Oceania.

As per usual, data that more closely represents real life is more interesting.
