Sensor Data Ingestion Interface Data Specification

Path

A Path contains a sequential list of PositionEstimates of the same or different Position Types, ordered by timestamps.

Note: Paths must contain at least one Position Estimate.
Figure 1. Path with a number of Position Estimates
Figure 2. Path with different types of Position Estimates

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.
