poi         


        

Answer 1

I couldn't understand your solution well, calculating the slope worked for me. To modify on efwjames's and your answer. This should do -

import math
def getDegrees(lat1, lon1, lat2, lon2,head):
    dLat = math.radians(lat2-lat1)
    dLon = math.radians(lon2-lon1)
    bearing = math.degrees(math.atan2(dLon, dLat))
    return head-bearing
