Python calculate bearing between two coordinates
I am attempting to calculate the bearing between two lat/long. Show I don't have a question regarding the function/formula per se, provided:
the problem is that the result isn't what is expected. The intended usage of the function returns the bearing between two lat/long pairs in a (very long) list i.e.
The bearing result then alters the view orientation of the plot where bearing can assume a value in the range [-180, 180]. Ideally, the result would appear such that the line formed between lat1, lng1 and lat2, lng2 is perfectly "vertical" in the plot (lat/lon annotations are switched in plot), see below I am hoping that someone might be able to deduce the problem from the bearing returned from the function and what the expected bearing should be. A few instances below:
Happy to provide additional information, thanks in advance for any/all help.

How do you find the bearing between two coordinates?Here is the formula to find the second point, when first point, bearing and distance is known: latitude of second point = la2 = asin(sin la1 * cos Ad + cos la1 * sin Ad * cos θ), and. longitude of second point = lo2 = lo1 + atan2(sin θ * sin Ad * cos la1 , cos Ad – sin la1 * sin la2)
How do you find the angle between two points in Python?The Python ATAN2 function is one of the Python Math function which is used to returns the angle (in radians) from the X -Axis to the specified point (y, x).. Since the gun and the target are defined relative to implicit x, y axes then tangent = (y2-y1)/(x2-x1) would be used. ... . You right, atan2 is a possible shortcut.. How do you calculate bearing headings?How to Calculate Bearing. True Bearing – Ship's Heading = Relative Bearing.. Relative Bearing + Ships Heading = True Bearing.. 225 – 59 = 166°. |
