Today I’m delighted to announce OpenFlights‘ coolest feature yet: KML exports.  KML, or “Keyhole Markup Language“, is the data format used by Google Earth and many other 3D visualization programs, so now you can turn your OpenFlights maps into this:

Exporting from OpenFlights couldn’t be much easier, just click on List flights and then hit the new KML button up top.  Load the resulting file in Google Earth — just double-clicking should do the trick — and there’s your map, in glorious 3D!    And if your planet looks a little too busy, you can tweak your OpenFlights filter and export, say, only one airline’s flights or only this year’s flights.

Airports are sized and color-coded, from big and yellow (busiest) to small and green (least visited), and you can click on them for more information.  Flight routes take into account the airport’s altitude and even approximate takeoff and landing paths, although runways and actual approach paths are not accounted for.

If you want to give 3D maps a shot before you start entering your own, download this sample (337 KB) and load it in Google Earth.  Tip: zoom into an airport and “tilt” the view with your middle button/scroll wheel to see the flight paths!

Anything else you’d like to see in your KML exports?  Let us know.

Going for a spin,
