I threw together a very short demo of a partial flight route — the low-level airway V316 from Ottawa to Sault Ste. Marie — overlayed on Google Maps using the new Google Maps API (I’ve also mentioned this in a posting on my flying blog). Each marker on the map is a navigation transmitter or intersection. This could look an awful lot better, but it’s still more interesting than the default Hello World app.
This is pretty simple stuff, but it’s a fun way to waste an hour or two on a holiday weekend. There’s a lot that could be done to make this look better, such as inserting frequencies for navigation aids and using custom marker icons.
