Get bearing from start point to end point

Supported in: Batch, Streaming

Calculates the absolute true bearing (clockwise angle relative to geographical north) from the first point to the second point in degrees using a spherical approximation of the earth.

Expression categories: Geospatial

Declared arguments

Ending point - Longitude and latitude for the ending point.
Expression<GeoPoint>
Starting point - Longitude and latitude for the starting point.
Expression<GeoPoint>

Output type: Double
