This invention teaches an inventive method for tracking trip data in relation
to geographic position for a vehicle. The first steps in the method involve recording
trip data periodically and recording geographic position periodically. Each trip
data recording is time stamped. Each geographic position recording is time stamped.
The next step is saving the recorded trip data and geographic position to a database.
The final step in the inventive method is graphically displaying the trip data
and the geographic position, as a function of time, from the database. This invention
also covers an apparatus and a system for carrying out the inventive method.
