Claim 9:
10. A method for estimating a location of a vehicle, the method comprising:
receiving a mapping between a first set of vertical vehicular data and a set of locations;
collecting a supplementary sensor dataset from a supplementary sensor of the user device;
determining a second set of vertical vehicular data based on the supplementary sensor dataset, wherein determining the second set of vertical vehicular data comprises scaling the supplementary sensor dataset based on a vehicular speed;
detecting that the second set of vertical vehicular data is a subset of the first set of vertical vehicular data;
in response to detecting that the second set of vertical vehicular data is a subset of the first set of vertical vehicular data, adjusting a sampling rate of a location sensor of the user device; and
determining an estimated location of the vehicle based on the second set of vertical vehicular data and the mapping.
