Claim 0:
1. A computer-implemented method of determining a geo-location, the method comprising:
determining, by a device, a floor-level outline of a floor of a first building depicted in a CAD drawing;
receiving, by a device, an approximate geo-location of the first building including the floor depicted in the CAD drawing;
obtaining, by a device, an overhead image of a target area encompassing the approximate geo-location of the first building, the overhead image comprising a plurality of buildings within the target area;
identifying, by a device, a plurality of building footprints each associated with a respective building of the plurality of buildings within the target area;
calculating, by a device, a plurality of different types of distance functions that relate the floor-level outline to each of the plurality of building footprints, wherein the calculating creates a plurality of similarity scores corresponding to relationships between the floor-level outline and the plurality of building footprints, and wherein each of the plurality of similarity scores corresponds to a combination of results of the plurality of different types of distance functions;
selecting, by a device, a building footprint from the plurality of building footprints based on the plurality of similarity scores; and
calculating, by a device, a final geo-location of the first building corresponding to the selected building footprint such that the final geo-location of the first building corresponds to a geo-location of one of the respective buildings of the plurality of buildings associated with the selected building footprint.
