Abstract: A method comprising: collecting a plurality of probe data from a plurality of probe points by a probing device, said probe data comprising at least positional information, a speed vector and a direction of travel of the probing device and a timestamp of recording the probe data at a probe point; and estimating a trajectory of the probing device between two consecutive probe points as a cubic Hermite spline having the positions of said two consecutive probe points as control points and the speed vectors of said two consecutive probe points as control vectors.

Abstract: An approach is provided for providing routing calculations and route guidance based on geographic positioning and/or other sensor data from one or more mobile devices independent of map data. A routing platform processes and/or facilitates a processing of one or more probe data samples associated with at least one mobile device to determine one or more device tracks. The routing platform processes and/or facilitates a processing of the one or more device tracks to determine at least one tessellation, wherein the at least one tessellation is a subdivision of a plane or sphere into one or more tiles and a plurality of segments. The routing platform further determines one or more relationships between one or more of the plurality of segments based, at least in part, on a mapping of the one or more device tracks against the at least one tessellation.
