1. A system for deriving three-dimensional coordinate data comprising: a computer which accepts a two-dimensional single image of an object, wherein the single image includes image data and is associated with an image geometry model (IGM); an analyzer that derives at least one set of three-dimensional metadata from the single image; a measurement utility that measures dimensions of the object by performing a projection measurement and a shadow measurement for the object, wherein the projection measurement is based at least in part on one or more of an IGM, height distance of the object, point-to-point distance of the object, line-of-sight distance of the object, volume, and bearing, and further wherein performing said shadow measurement includes determining a length of the shadow of the object based on a height of the object and an altitude of the sun; and a model generation utility that derives three-dimensional coordinate data based at least in part on the projection, the shadow, and the three-dimensional metadata.
