Description Usage Arguments Details Value Author(s) References Examples

Calculates Bearing given initial latitude and longitude and ending latitude and longitude in decimal degrees and returns bearing in radians.

1	CalcBearing(initialLat, initialLong, finalLat, finalLong)

`initialLat`	initial Latitude
`initialLong`	initial Longitude
`finalLat`	ending Latitude
`finalLong`	ending Longitude

Data must be provided in decimal degrees (e.g. 162.546). Longitude values west of the prime meridian are 0 to -180. Latitude values south of the equator are 0 to -90. As one travels from point A to point B, the bearing to point B changes. This function calculates the bearing from point A to point B at point A. This function is primarily used internally in the GPStable and GeoReference functions.
