The Giza Plateau Mapping Project, under the direction of Mark Lehner, Visiting Assistant Professor of Egyptian archaeology at the Oriental Institute, is dedicated to research on the geology and topography of the Giza plateau, the construction and function of the Sphinx, the Great Pyrimids, the associated tombs and temples, and the Old Kingdom town in the vicinity. Lehner is a pioneer in the use of state-of-the-art computer graphics and remote sensing technology to model the ancient configuration of the Giza Plateau. In addition he has collaborated with an architectural firm to produce a detailed computer model of the Sphnix which is of exceptional value both as a research tool and to guide current conservation efforts.
