About the bearing calculation for map

[aktay]

Dear All,

I'm trying to make navigate. But I have no idea how to use the bearing feature. How should I calculate the bearing, what conditions should I consider when calculating, and what should my calculation criteria be?

Any idea on this issue?

Thanks.

Hi,

What do you mean by "make navigate" ?

Sorry , I mean navigation. I've already solved the problem.

I am using the following JavaScript code.

        var firstLatitude=deg2rad(latitudeArray[latitudeArray.length-2]);
        var firstLongtitude=deg2rad(longtitudeArray[longtitudeArray.length-2]);
        var endLatitude=deg2rad(latitudeArray[latitudeArray.length-1]);
        var endLongtitude=deg2rad(longtitudeArray[longtitudeArray.length-1]);
        var diffLongtitude=(endLongtitude-firstLongtitude);
        var x=Math.sin(diffLongtitude)*Math.cos(endLatitude);
        var y=Math.cos(firstLatitude)*Math.sin(endLatitude)-Math.sin(firstLatitude)*Math.cos(endLatitude)*Math.cos(diffLongtitude);
        var bearing =(rad2deg(Math.atan2(x,y)));
      if(bearing!=0){
        angleData=bearing;
}
