Active Addressing

All tracking hardware transmits location information as latitude / longitude pairs, e.g. latitude = 51.503156 and longitude = -0.127571. This is all the information that's needed to plot the location visually on a map, but it isn't suitable for describing where that location is.

Reverse Geocoding

Reverse geocoding is the process of converting a latitude/longitude location into a meaningful address. So reverse geocoding the latitude and longitude above would produce 10 Downing Street, Westminster, London, SW1A 2AA - something that's much more recognisable and usable in a report or alert, for example.

Fleet tracking services typically fall into one of three categories:

  1. No reverse geocoding
    Current and historical information is only shown visually on a map.
  2. Partial reverse geocoding
    Only the start and end locations in a journey are converted into an address, typically for display in a summary table.
  3. Full reverse geocoding
    Every position is reverse geocoded into an address.

The Maptex fleet tracking service reverse geocodes every position as soon as it is received from a device, something we term active addressing.

Advantages of Active Addressing

There are several advantages to be gained by actively addressing every position.

Journey Details

Having address details for every position received from a device allows us to present a detailed description of each journey, including the date/time, address, speed, heading, as well as other information.

This information can be a useful format in which to archive details of an individual journey.

Alerts With Addresses

Having the address details readily available also enables us to provide rich alerts when geofences are breached, or analog or digital alerts occur.

Examples of a common alarm format is shown below:

"Panic button pressed on vehicle V123 45Y at STAMFORDHAM ROAD, BLAKELAW, NE5 2SF at 03/08/2009 19:24:47"
