Web/API/GeolocationCoordinates/heading

Secure contextThis feature is available only in secure contexts (HTTPS), in some or all supporting browsers.

The GeolocationCoordinates.heading read-only property is a double representing the direction in which the device is traveling. This value, specified in degrees, indicates how far off from heading due north the device is. Zero degrees represents true true north, and the direction is determined clockwise (which means that east is 90 degrees and west is 270 degrees). If GeolocationCoordinates.speed is 0, heading is NaN. If the device is not able to provide heading information, this value is null.

Syntax

let heading = geolocationCoordinatesInstance.heading

Value

A double representing the direction in which the device is traveling.
