Abstract
A computer implemented method for three-dimensional volumetric indoor location geocoding relative to a geographic location is provided. The method includes: creating a three-dimensional representation of the geographic location; notionally subdividing the three-dimensional representation into an array of discrete elements; receiving an address and converting the address into geographic coordinates; querying the array of discrete elements representing the geographic location; determining a list of all discrete elements with at least one of a matching address and sub-address element attribute; generating a notional minimum bounding three-dimensional polygon containing the matched discrete elements with the at least one matched address and matched sub-address element attribute; determining a list of geodetic coordinates defining the minimum bounding three-dimensional polygon; and presenting the list of geodetic coordinates defining the minimum bounding three-dimensional polygon.
