iOS Question What's the difference between heading and bearing?

    After using B4A I thought that heading was the direction (in degrees) you are facing, and bearing was direction (in degrees) to a target.

    The B4i tutorial has only 1 location in it, and the results sometimes give a bearing. What is this bearing??

    The reason I ask is because I'm trying to do a bearingTo.

    This is the bearing code in the tutorial:
    Code:
    lblBearing.Text = ValueOrNA (Location1.Bearing, 1Chr(176))
    I thought that changing location1 to targetLocation would work. I don't think it does, so I think I don't understand bearing.
    I think I've set up my targetLocation ok because
    Code:
    Location1.DistanceTo(targetLoc)
    works fine.

    I am aware of the other thread about this here http://www.b4x.com/android/forum/threads/calculate-bearing-to-other-location.46513/#post-291737 and am currently going through it trying to understand what is going on. eg what the variable cPI is (edit in case anyone else gets here looking for cPI - this is the B4x constant for Pi)

    Location.Bearing returns the traveling direction. If you are driving north then it will be north.
