question about bearing

[zbeekman]

Is the bearing the compass bearing at point A to begin the great circle/geodesic route to point B?

Is there an easy way to get compass bearings as a function of distance traveled from point A? (i.e. along the entire route, from the outset?)

Obviously any nav-guidance system could just recalculate bearing at each location as it transits the great circle, but I'm curious if your tool can provide this info at the outset.

Thanks!

Hi,

The "destination" function together with bearing may be of help in your situation. You can calculate the initial bearing, use that to calculate coordinates of a point on that bearing, specific distance away, then calculate new bearing from that point. Hope this helps.
