Two comments. 1) This appears to be only airports that offer commercial passenger service. 2) Easter Island has an airport! I was under the impression you could only get there by boat.

I flew to IPC (aka Easter Island Airport) in 2013. It actually has a massive runway due to being a Space Shuttle diversion site, although the terminal itself is a glorified shack. Flying there (from Santiago) was a bit terrifying knowing how far away you are from any alternate airport, or any civilization at all really.

Curious if there's any region smaller than that of LaGuardia Airport. A glance doesn't find any.

L'Esperance and (maybe?) Caye Caulker airport are smaller.

This is awesome, and I really wish it would give me information on which airport each tile represents.

You can hover over a tile to get the airport's name.

This runs slower on my computer than MGSV in ultra settings running on 4k resolution.

well it is rendered via the dom you can't really expect much the information is pretty cool though .. i'd would be neat to see something like this done with cesium

I thought that a voronoi partition is not possible with only straight lines on a non-euclidean space like that; this leaves me confused.

They must be geodesics, not straight lines

The edges are segments of great circles, which are the reasonable equivalent to a straight line on the surface of a sphere.

It looks like you still just use delaunay triangulation on the points on the surface of the sphere. And then he is connecting the resulting vertices with lines along the surface of the sphere. The lines look straight from head on, but are curved in 3d space.

Easter Island doesn't just have an airport on it, it's got an airport with a runway built long enough to accommodate the Space Shuttle.

It's an awesome place to visit - a town of a few thousand people, surprisingly good food, breathtaking moai, and due to its relative remoteness, not particularly crowded with tourists. I liked it enough to want to go back.
