Claim:
1. A method of determining the location from which images were captured, the method comprising: obtaining, by one or more processors, a plurality of distance-referenced images, each distance-referenced image captured from a different position among a plurality of positions; determining, by the one or more processors, locations of the plurality of positions in a shared coordinate system by calculating a difference between a first distance and a second distance, wherein the first distance is measured from a first position among the plurality of positions in an orientation, and the second distance is measured from a second position among the plurality of positions in a same orientation as the first distance; and associating, by the one or more processors, the determined locations with corresponding images of the distance-referenced images in spatially-referenced images stored by a spatially-referenced image repository.
