Mapping II

How are the surface remains of buildings and other architectural elements at Vijayanagara recorded?
David Gimbel describes in detail the technical aspects of Archaeos' surveying work: shooting points using a theodolite, a prism, and a digital data collector with custom-written software. We see how decisions are made to create the most accurate 2-D and 3-D models possible using a variety of geometric considerations and a pre-determined set of architectural feature codes.
