We are developing a tracking software and we are the stage where we test the reliability of our location stigma on the following web-maps
- Google Map
- Nokia HERE
- Open Street Map (OSM)
We observe that our location appears accurate on Google maps, however when switched to Nokia or Openstreet there is a discrepancy of around 40-50 metres from our actual location. Most importantly our GPS position accuracy is around 2m.
Could it be inaccuracy of map calibration or any similar problems known by anyone?
