How do I calculate the Azimuth (angle to north) between two WGS84 coordinates

Question

I have got two WGS84 coordinates, latitude and longitude in degrees. These points are rather close together, e.g. only one metre apart.

Is there an easy way to calcu

Answer 1

I would recommend implementing a correction factor based on the longitude. I implemented a simular routine once to return all geocoded records within x miles of a specific spot and ran into simular issues. Unfortunately I don't have the code anymore, and can't seem to recall how I got to the correction number but you are on the right track.
