Path contains a sequential list of PositionEstimates of the same or different Position Types, ordered by timestamps.
A path can be very short or very long, depending on the Path Events that occur on the way:
- Near real time events are transmitted immediately after they occur and generate a very short path.
Example: For a speed limit sign, a Sign Recognition Path Event is immediately created. The Path starts Position Estimates at a defined distance before the actual event and should include two Position Estimates after the event.
- If a drive lasts many hours, record the vehicle trace and events for later submission. This results in very long paths.
For an example of a path structure, see Sample Message.
