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.

An approach is provided for hierarchical clustering of geographical data. The approach involves receiving a request to cluster geographical data by location. The geographical area is represented by a hierarchical tile projection comprising a plurality of zoom levels, and tiles of each of the zoom levels represent different respective scales of a corresponding portion of the geographical area. The approach also involves determining that the geographical data is located in a border area of a first tile at a higher zoom level of the hierarchical tile projection. The approach further involves recursively forwarding the geographical data for clustering at a lower zoom level of the hierarchical tile projection until the geographical data is not located in a border area of a second tile at the lower zoom level. The approach then involves initiating the clustering of the geographical data into a cluster located in the second tile at the lower zoom level.
