Various embodiments are directed to determining an elevator car position within an elevator shaft using footprint representations or descriptions of frequency spectrum data at reference positions along the elevator shaft. In one aspect, an example method is provided. The method includes determining reference frequency spectrum data for each of a plurality of reference positions along the elevator shaft and generating a footprint associated with each reference position based at least in part on a plurality of frequency peaks within the reference frequency spectrum data for each reference positions. The method further includes obtaining real-time frequency spectrum data associated with the elevator car within the elevator shaft and determining an estimated position of the elevator car based at least in part on comparing the real-time frequency spectrum data with a plurality of footprints associated with the plurality of reference positions.
