Do aircraft transmit their track as 0 degrees, or 360 degrees when heading north?
I'm using a separate icon for every degree when plotting on google maps which essentially starts at 0.png, all the way up to 359.png. I just noticed in my webserver logs that there's been numerous instances where 360.png was not found. I would have thought they'd transmit North as 0 degrees, rather than 360 degrees.
