[geonet]: Find the heading going down a line

[skyhunter]

Hi all,   Does anyone know of a way to obtain the heading between fiducials for a flight line. For instance, I have a flight path that turns on line and I want to see if I can detect when the plane actually begins the line by calculating the heading between time 1 and time 2, time 2 and time 3, etc and detecting when the line begins as when the heading equal 180 degrees.     Aaron Balasch Sky Hunter Technologies Inc.
