A detailed 3D Google Earth model of the ancient Inca city of Machu Picchu has been created using data from a laser scan of the site conducted by the University of Arkansas (see below). The model contains every building, every structure and every terrace in the entire city and is accurate to within 10cm (4″) over most of the site. The model also includes all structures and terraces at the top of Wayna Picchu, the mountain that is in the background in most photos of Machu Picchu. The video includes a series of photos of Machu Picchu together with screen shots of the model to show the accuracy of the model. (The dark coloured texturing of the grass etc. is taken directly from the Google Earth satellite image, which is required by Google.) There is a stereoscopic 3D version of the video at www.youtube.com Data developed under the authority of the Instituto Nacional de Cultura, Vladimir Dávila – Arquitecto del PAN Machu Picchu, Director del PAN Machu Picchu Direccion Regional de Cultura Cusco and Fernando Astete – National Archaeological Park of Machu Picchu. Data acquired, processed and distributed by the Center for Advanced Spatial Technologies staff (Snow Winters, Malcolm Williamson and Katie Simon) and by students in the 2009 Cotsen Institute for Archaeology (UCLA) Cuzco/Machu Picchu Field School, Alexei Vranich Director.
