4.1 List Tracks

Click the List tracks button to see any new locations. The page is not automatically refreshed when a new location is received.

Restricted Sharing: When a user shares their tracks with you, they can restrict how far back you can view their track points. In that event, the date range shown at the top of the page may be reduced to show the actual time period being viewed.

The following data is shown for each location. The values are those sent from the device. The units for those values are assumed to be as follows:

• Time–localised to the web browser’s time zone.
• Latitude/Longitude–location using the WGS84 geodetic reference system.
• HDOP–Horizontal Dilution of Precision–estimated horizontal accuracy in metres.
• Altitude–metres.
• Speed–metres-per-second.
• Bearing– degrees.
• Note–optional text entered by the user for the location.
• Provider–optional data provider, e.g. GPS, Network.
• Satellites–Optional value indicating how many satellites the fix was using.
• Battery–most recently recorded battery percentage for the GPS device, where available.

To convert the speed to kilometres-per-hour, multiply by 3.6. To convert the speed in metres-per-second to approximate miles-per-hour, multiply by 2.24. For an exact conversion to miles-per-hour, multiply by 3,600 then divide by 1,609.344.
