Coordinates

A set of properties that describe the geographic coordinates of a position.

Properties

  • latitude: Latitude in decimal degrees. (Number)

  • longitude: Longitude in decimal degrees. (Number)

  • altitude: Height of the position in meters above the ellipsoid. (Number)

  • accuracy: Accuracy level of the latitude and longitude coordinates in meters. (Number)

  • altitudeAccuracy: Accuracy level of the altitude coordinate in meters. (Number)

  • heading: Direction of travel, specified in degrees counting clockwise relative to the true north. (Number)

  • speed: Current ground speed of the device, specified in meters per second. (Number)

Description

The Coordinates object is attached to the [Position](../Position/position.html) object that is available to callback functions in requests for the current position.

Supported Platforms

  • Amazon Fire OS
  • Android
  • BlackBerry WebWorks 5.0+
  • iOS
  • Tizen
  • Windows Phone 7 and 8
  • Windows 8

Quick Example

// onSuccess Callback
//
var onSuccess = function(position) {
    alert('Latitude: '          + position.coords.latitude          + '\n' +
          'Longitude: '         + position.coords.longitude         + '\n' +
          'Altitude: '          + position.coords.altitude          + '\n' +
          'Accuracy: '          + position.coords.accuracy          + '\n' +
          'Altitude Accuracy: ' + position.coords.altitudeAccuracy  + '\n' +
          'Heading: '           + position.coords.heading           + '\n' +
          'Speed: '             + position.coords.speed             + '\n' +
          'Timestamp: '         + position.timestamp                + '\n');
};

// onError Callback
//
var onError = function() {
    alert('onError!');
};

navigator.geolocation.getCurrentPosition(onSuccess, onError);
