# Infering course given origin and destination coordinates

I have two points. A vehicle is at point A and I have the coordinates at point A. The vehicle moves to point B and I know the coordinates as well.

I would like to find the angle of movement i.e., 0,180,90,45,360 degrees etc. With the angle, I can tell in what direction its headed relative to origin.

Given that I know the coordinates at A and B, how would I calculate the degree between point A and B.

• I am not using any program. I am reading this igismap.com/… to calculate bearing and i want to test with real data and see whether the formulas work. May 20, 2019 at 17:20

• This is more than a little complicated, with the formal name of the Inverse Geodetic Problem May 20, 2019 at 18:21

Do like sailors did in the past: take a mercator map that has the two locations on it, draw a straight line between the two points and measure using a protractor the angle with a meridian, that angle is your bearing.
