The View Across The Ocean Is Not What You Think 

The View Across the Ocean Is Not What You Think

Coastlines are ragged, messy things, twisting and turning every which way. As a result, what’s “directly across the ocean” from you depends on where you’re standing on a rather fine scale. It also depends on the curvature of the Earth.

It’s easy to forget that we live on a curved ball — and some people never seem to have learned it — but a recent series of maps by cartographer Andy Woodruff offers a mind-bending reminder. His “Beyond the Sea” collection shows us who we’d really be waving to if we could see land at the other end of the watery horizon. Think that’s Europe out there, New Yorkers? It’s actually Brazil. San Franciscans have a lovely view of Australia, while it’s a straight shot from Vancouver Island to the lonely, icy margins of Antarctica.

As Woodruff explains:

If you can detach the concept of “direction” from the concept of east and west, and look at globes and other map projections, it’s easy enough to picture. The shortest, straightest line on a sphere (let’s call the Earth a sphere even though it technically isn’t) is a great circle arc, not something like a line of latitude.

So if we want to know what’s truly straight across the ocean from a given coastline point, we need to see what direction the coast faces at that point, then draw a great circle in that direction and see what it runs into.

Wondering what lies across your local shoreline? Check it out on one of the maps below — each one indicates views to the labelled continent. Perhaps you’ll be surprised by what you find.
