# Get bearing from start point to end point

> Supported in: Batch, Faster, 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.<br>*Expression\<GeoPoint>*
* **Starting point:** Longitude and latitude for the starting point.<br>*Expression\<GeoPoint>*

**Output type:** *Double*

## Examples

### Example 1: Base case

**Argument values:**

* **Ending point:** `end_point`
* **Starting point:** `start_point`
