How to read this
Direction
The compass point is where to face from the middle of the place, and the degrees say how far to look up: 0° is the horizon, 90° is straight overhead.
Who counts
Aircraft whose transponders reach a volunteer receiver. Coverage is good over cities and thin in remote places. Military and government aircraft are listed when they broadcast; private aircraft whose owners opted out of public display (FAA LADD, PIA) are not.
