Maps

Excellent xkcd today (it’s always excellent).

I just want to say that I learned something about the details of how effed up the Earth’s surface is when I tried to implement a few different distance-calculation algorithms.

The Earth isn’t a sphere, the Earth isn’t even an ellipsoid. The Earth is a GEOID, an object made up expressly for the purpose of describing how screwed up the topography is on this gigantic gravity-glued rock floating through the void.
