# bearing

A **bearing** is the direction you're facing, measured clockwise as an angle from true north on a compass. This can also be called a *heading*. In this system, north is `0°`, east is `90°`, south is `180°`, and west is `270°`. When you are viewing a Mapbox map, the bearing rotates the map around its center the specified number of degrees.

The bearing of your map view can be adjusted in many Mapbox products, including [Mapbox Studio](https://docs.mapbox.com/studio-manual/), [Mapbox GL JS](https://docs.mapbox.com/mapbox-gl-js/), the Mapbox Maps SDKs for [Android](https://docs.mapbox.com/android/maps/) and [iOS](https://docs.mapbox.com/ios/maps/), and the [Static Images API](https://docs.mapbox.com/api/maps/static-images/).

The bearing of a vehicle as it starts from a waypoint can also be set in the [Directions API](https://docs.mapbox.com/api/navigation/directions/) and the [Optimization API](https://docs.mapbox.com/api/navigation/optimization-v1/) using the optional `bearings` parameter, and in the [Mapbox Navigation SDKs](https://docs.mapbox.com/ios/navigation/) for iOS and Android.
