MyGeotab IFTA report uses a sophisticated form of reconciliation to combine ECM odometer with GPS data. A fuel tax detail for a vehicle is identified by its Enter and Exit time. Each detail starts when and where the previous, if any, detail ended. Each detail contains a set of parameters at both ends of its time interval, as well as at each hour within that interval. The parameters include:
- Odometer values, based on engine status data.
- GPS Odometer values, based on distances between GPS records.
- Latitude and Longitude.
