  • Determining elevation values in a geocoding system
    Patent number: 7526379
    Abstract: A system and method of determining elevation values includes inputting a location into a geocoding system having a segment data set and determining the closest segment in the data set to the location. A data set of elevation data the closest segment is accessed and a determination is made of an elevation value for each of two elevation points associated with the closest segment. The elevation value of the location is determined based on interpolation of the location in relation to each the two elevation points and the elevation value of each of the two elevation points. The determined elevation value for said input location is output. The offset distance of the location from the closest segment may be determined and a slope applied to the offset distance to determine an elevation gain or loss for the location due to the offset distance of the location from the closest segment.
