The geographical location is displayed on the device in the form of latitudinal and longitudinal coordinates (in WGS-84 standard format). When the location of the device changes, you can receive updates about the changes. If the device supports this feature, you will be able to obtain information about the altitude, accuracy, heading, speed, and timestamp of the latest change in the location.
