MEXICO CITY.- Emblematic Mexican constructions such as the Metropolitan Cathedral, Palacio Nacional, Padre Tembleque Aqueduct and San Juan de Ulua Fort have been digitalized by the National Institute of Anthropology and History using the laser scanner method, becoming a pioneer in Latin America. As part of the seminar that took place at Templo Mayor Museum, in Mexico City Historical Center, different projects that have used the 3D Laser Scanner technology to conform a digital database of historical and archaeological constructions in Mexico were made known.
