1. A surveying system for determining the location of an object point from images, said surveying system comprising: two image gathering devices coupled at a known relative distance, each said image gathering device adapted to generate an image; a global positioning system providing an absolute position of a first capture point; and a location calculator, said location calculator having a plurality of instructions enabling said location calculator to correlate at least two reference points appearing on two images obtained with the two image gathering devices at the first capture point with reference points appearing on images obtained at a second capture point to obtain correlated reference points, and to determine the position of the object point based on the correlated reference points and the absolute position of the first capture point.
