Claim 11:
12. The method of claim 2, wherein the processing the correlated foot data to determine the elevation tracking for the time period comprises:
determining a first z coordinate from a first three-dimensional foot data point that corresponds to a beginning of the time period;
determining a next z coordinate from a next three-dimensional foot data point that corresponds to a next sampling point of a sampling clock within the time period;
determining a next delta distance based on a difference between the first z coordinate and the next z coordinate;
when the next delta distance is greater than or equal to zero, adding the next delta distance to an accumulation of previous delta distances to produce an updated accumulation of delta distances;
when the next sampling point corresponds to an end of the time period, provided the updated accumulation of delta distances as an elevation change that occurred during the time period; and
when the next sampling point does not correspond to the end of the time period, repeating all but the determining the first z coordinate from the first three-dimensional foot data point that corresponds to the beginning of the time period for another next three-dimensional foot data point until the next sampling point corresponds to the end of the time period.
