Abstract: Embodiments includes systems and methods for referencing a dynamic closed geometry event to a map tile for a navigation application. The dynamic closed geometry event changes in geographic coverage area over time. In response to receipt of data indicative of the dynamic closed geometry event in map agnostic coordinates, a processor, identifies a map tile level for the navigation application and identifies at least one map tile identifier for the dynamic closed geometry event. Multiple map tile offsets are calculated based on the map tile level and the dynamic closed geometry event and sent to the navigation application.

Abstract: A method is provided that includes: receiving a plurality of estimated position points, each estimated position point including a timestamp, where each estimated position point is an estimate of a position of a vehicle at a time respective timestamp; receiving on or more path events, where each of the one or more path events includes a timestamp and data from at least one sensor of the vehicle; generating a path from the plurality of estimated position points, where the estimated position points are arranged in order of ascending time represented by the respective timestamp; and interpolating between two of the estimated position points to determine a location corresponding to one of the one or more path events, where the timestamp of the one of the one or more path event corresponds to a time that is between the times represented by the timestamps of the two estimated position points.
