Is there a way to calculate angle between two Latitude/Longitude points?
What I am trying to achieve is to know where the user is heading. For example, user is heading North, South,.... South-East, etc.
But I have only two points (Lng/Ltd)
Thx

I think you want the calculations for the Great Circle bearing.

Hi HPM, no I do not need Great circle bearing. Just need the angle :)

@praethorian -- two Latitude/Longitude points define (an arc of) a Great Circle, you'll have to explain what you mean by the angle between them.
