GreatCircleMaths.Bearing Method

GreatCircleMathsBearing Method

Given two points on the earth's surface this calculates either the bearing to take from point A to get to point B. It can optionally take a pre-calculated bearing and return that if the start and end points are the same.

static member Bearing : 
        startLatitude : Nullable<float> * 
        startLongitude : Nullable<float> * 
        endLatitude : Nullable<float> * 
        endLongitude : Nullable<float> * 
        currentTrack : Nullable<float> * 
        reverseBearing : bool *

Parameters

startLatitude: Type: SystemNullableDouble
startLongitude: Type: SystemNullableDouble
endLatitude: Type: SystemNullableDouble
endLongitude: Type: SystemNullableDouble
currentTrack: Type: SystemNullableDouble
The brearing to return if ignoreCurrentTrack is false and the start and end points are the same.
reverseBearing: Type: SystemBoolean
True if the bearing should be reversed.
ignoreCurrentTrack: Type: SystemBoolean
True if the bearing should always be calculated and possible shortcuts ignored.

Return Value

Type: NullableDouble
