Hey everyone,

I recently finished building www.greatcirclemap.com.

The website lets you enter airport codes or names of cities and it then plots the great circle path between the airports on a map. If you've ever used www.gcmap.com or www.greatcirclemapper.net you know the concept. I have personally spent countless hours on these sites, but I thought they could be improved upon:

Gcmap.com is nice but the map-image is small and doesn't let you zoom in since it's just an image. Greatcirclemapper.net is zoomable since it uses google maps but is painfully slow because the entire page has to reload every time you put in more routes.

greatcirclemap.com should be much faster than both of those sites since it never reloads the page. If you type in a route, it will appear instantly.



TIP: Check the “Raw input”-toggle if you already know the airport codes. It will let you input ICAO- or IATA-codes manually so you don't have to bother with auto-complete. It should work exactly like gcmap.com.

If you have any suggestions or feedback, I would greatly appreciate it! Seriously, I've put in so much time in this project, so if you have any feedback at all I'd love to hear it.
