Explore Online! MIT Team Digitizes Historic Sanctuary of Machu Picchu
For many people, the Inca city of Machu Picchu in the Andes of Peru is one of the most recognizable icons of archaeological and adventure tourism in the world. However, for the Peruvian people and for the international scientific community, Machu Picchu is much more than a tourist destination. In addition to being a United Nations Educational, Scientific and Cultural Organization (UNESCO) World Heritage Site, the historic sanctuary has great cultural and economic importance for Peru and the region of Cusco.
The first references to attempts to document the city of Machu Picchu date back to the late 19th century, when Peruvian and European explorers toured the rugged mountains around the meandering Urubamba River. Some of the explorers did not hesitate to register their visit in the rock. On a wall of the Temple of the Three Windows, Agustin Lizarraga recorded, “July 14, 1902”.
But it was Yale University Professor Hiram Bingham who extensively documented the site during his expedition in 1911, and made known to the international community the existence of the lost ruins of the Incas. Over the last 100 years, dozens of archaeological expeditions have contributed to increasing the architectural value and interest in the site, as well as the scientific knowledge of the extraordinary technologies developed by the Incas.
In order to digitally document and develop the foundations for future research, a laboratory team from the MIT Department of Architecture, led by Professor Takehiko Nagakura and PhD student Paloma Gonzales, has been working on the MISTI Global Seed Fund Machu Picchu Design Heritage project since 2016.
The team, the Architecture Representation and Computation Group, has led the first extensive expedition to digitally document Machu Picchu, using the latest generation of instruments and techniques to explore the site’s architectural and urban importance and develop a 3-D site map using virtual reality and augmented reality. The Architecture Representation and Computation Group has an important record of working with digital capturing technologies on World Heritage Sites in Italy, China, Singapore, and Japan.
“We believe that documentation through computational techniques for the digitalization of architectural monuments is key to the preservation of the cultural heritage of humanity,” Nagakura says. “But it is just a simple idea for old practice. From Renaissance time, architects have been going to building sites, and drawing them up to study them. We are just replacing tape measures and Mylar sheets with scanning tools and VR headsets.”
For the project in Peru, the team visited the archaeological complex on two occasions for several weeks in mid-2017 and early 2018. At the site, more than 9,000 images were collected through panoramic cameras, photogrammetric scanning tools, and drones. Gonzales says the working hours were “intense.”
“We had to reach the archaeological monument before the arrival of the tourists and stay after the closure of the monument,” she says. “The great commitment and joint work of the MIT team and the San Antonio Abad del Cusco University, supported by the Decentralized Directorate of Culture of Cusco, made the work fruitful and rewarding.”
Based on the photogrammetric data they sampled, the team developed 3-D models and are working on creating virtual reality experiences that would allow people to immerse themselves in Machu Picchu from anywhere on the planet. The same 3-D models are also being deployed to make a new interactive map of Machu Picchu that superimposes the photographic 3-D view of the site through augmented reality.
Last December, the team launched the MIT Design Heritage Platform, where visitors can see and explore part of the work they have done. In addition, they plan to make this platform a tool to collect images from those who can contribute to the data bank through crowdsourcing.
The project has also managed to document the architectural characteristics and construction materials of the city with high-resolution photographic techniques. The images constitute a unique database with rich information on aspects such as landscape and vegetation at the time the photographs were taken. The team will make all of the information collected available to the authorities of the archaeological monument.
