As you would expect the system has both a live tracking function and historic track view.
The system makes use of Microsoft Silverlight to display the vehicle locations on the map as well as any other info reported from the vehicles such as Ignition On or Off, Speeding etc, as the vehicles report to the server you see them moving on the map.
You can display a single vehicle, all vehicles or if you have used the settings section to group your vehicles you can display just specific vehicles.
Within the same section you can display all sorts of helpful info such as speed graphs, mileage for any period you choose, periods of inactivity and so much more. If there is something specific you want from the data please ask, the system probably does it.
