A team of archaeologists led by researchers from Binghamton University has combined over 22,000 images of the primary quarry on Rapa Nui (Easter Island) to create the first-ever interactive 3D model of the remote site, allowing users to explore its archaeological marvels in unprecedented detail.
Unlike the more famous coastal platform that contains over a dozen Moai statues facing the ocean, the 3D model’s creators chose the Rano Raraku quarry because it contains over 1,000 statues in various forms of completion. The study also found evidence that the quarry was used by several different “tribes” working alongside each other.
“As an archeologist, the quarry is like the archeological Disneyland,” explained Binghamton University Professor of Anthropology Carl Lipo, lead author of the paper detailing the team’s work and member of a previous research team that proved the statues were ‘walked’ into place.
The team hopes their new 3D model will allow researchers to conduct studies in an extremely difficult-to-access area and to attract the attention of curious amateurs who may visit the island in person.
Building the Easter Island Moai Quarry 3D Model from Thousands of Images
According to a statement detailing the effort, the project began in October 2023 after a wildfire swept through the area, prompting locals to implore the scientific community to document the location. The Binghamton-led team, which also included Thomas Pingel and Kevin Heard from Binghamton’s Geography Department, responded by conducting the first-ever in-depth digital documentation of the quarry in January 2024.
Over 30 drone flights, the researchers collected high-resolution images from a wide range of perspectives, including angles unavailable to a ground observer.
“You can see things that you couldn’t actually see on the ground,” Professor Lipo said. “You can see tops and sides and all kinds of areas that just would never be able to walk to.”
By the completion of the aerial sorties, the team had successfully captured around 22,000 images of the Rapa Nui quarry at 30-meter increments. Pingel said it was amazing how far the technology that allowed the team to collect the data used to create an interactive 3D VR model of the quarry has come in such a short time.
“The quality of this model is far above what could be done even just a couple of years ago, and the ability to share such a detailed model in a way that is accessible from anyone’s desktop computer is remarkable,” the researcher explained.
“The project was of a scale of complexity that had never been attempted before,” Professor Lipo added.
Users who want to explore the model will find a variety of built-in controls and functions, including the ability to zoom in and pan across individual statues and quarry features from numerous angles. Because the Rano Raraku quarry is located within a rugged, steep volcanic crater, the team said that traversing it on foot is too dangerous, making the 3D VR model of this remote location a priceless research tool.
“It has everything you can possibly imagine about moai construction, because that’s where they did most of the construction,” Professor Lipo said when describing the remote Easter Island quarry. “It’s always been this treasure of information and cultural heritage, but it’s remarkably underdocumented.”
Model Could Aid Researchers and Entice Visitors
When discussing the potential uses of their new interactive 3D VR map of the Easter Island Moai statue quarry, Lipo said their model could “open the door” for researchers by providing a three-dimensional replica and allowing everyday people the unusual opportunity to ‘visit’ the island without leaving home.
“We can say, ‘Here, go look at it.’ If you want to see the different kinds of carving, fly around and see stuff there,” the professor explained. “So, it’s really exciting to bring these two things together. We’re documenting something that really has needed to be documented, but in a way that’s really comprehensive and shareable.”
The researchers acknowledge that some locals have expressed concern that such a high-quality map may reduce tourism and eliminate the desire to see the site in person. However, Professor Lipo believes the detail and interactivity with the nearly 1,000 moai in a way previously unavailable will inspire people to go there in person and explore all of the wonders associated with the Island and its awe-inspiring sites, “because otherwise, you’re just seeing sort of snapshots of stuff.”
“What we would really like to do is be able to say, ‘Go visit it yourself. Learn from it,’ the researcher concluded. “This is an incredible landscape of stuff that you could really go visit, that you’ll want to see.”
