Location Location Location

The GPS function with Traffic4England is designed to provide an approximate location to base the traffic events.

Depending on when and where you use the GPS system, the accuracy will be anywhere between within 5 meters to within 5000 meters. Then android gets a GPS 'fix' it then attempts to do whats call reverse geocoding, which effectively calls the Google Map servers and ask them if they've an address for the current longitude/latitude position. Somethings there will be a full address, sometimes where won't, somethings it will be within 5 metres of where you are, sometimes it won't. The accuracy varies depending on where you are.

The GPS feature is there to provide a 'best effort' at placing your location so that the distance to the nearest traffic events realistic. Depending on the prevailing conditions, sometimes it will be accurate, sometimes it won't.

If you need to check, fire up the standard Google maps on Android and use the locate function. Tap the 'current location' marker to get it to show the accuracy in meters of the current GPS reading. This reading is effectively the best Traffic4England can do.
