The Making of Digital El Camino Real
Traverse the 600-mile trail that connects California’s 21 missions. Peer behind an ornate mission altarpiece that, for more than two centuries, has hidden murals painted by the Ohlone Indians. Uncover the mysteries of Mission Dolores’ ancient cemetery.
Like Interstate 101
“Some people think the Camino Real means the Royal Road of Jesus in California,” says Andrew Galvan, curator of Mission Dolores, San Francisco. “No. It was the King’s Highway, the King of Spain’s highway.”
Mission Dolores, founded in 1776, is the oldest surviving structure in San Francisco and one of the first sites along the historic El Camino Real to be scanned and documented by CyArk.
“If you step out the front door of Mission Dolores you are on the El Camino Real,“ says Andrew. “It was a public road, like Interstate 101. All the California Missions are connected. Wherever you got on it, the road led you to the Viceroy’s Palace in Mexico City.”
CyArk’s Laser Scanning Mission
CyArk has digitally preserved over 70 sites around the world from Pompeii in Italy, to Tikal in Guatemala.
“We use a 3 D laser scanner that sends out a pulsed laser beam and captures billions of points of these structures at a rate of about 100,000 points a second,” explains Elizabeth Lee who directs operations at CyArk. These sites are at risk, endangered due to everyday exposure to the elements, vandalism, war, urbanization, poorly managed tourism, catastrophic events, and general neglect.
The non profit organization was founded in 2003 by Ben and Barbara Kacyra after they sold their technology company that had developed the first fully integrated laser 3D imaging, mapping, modeling, and CAD system which is currently used worldwide in architecture, engineering and construction, entertainment and crime forensics.
“It was right at the time that the Bamiyam Buddhas were blown up by the Taliban,” remembers Barbara Kacyra. “There was no 3 dimensional documentation of them. We said, ‘How can we use this technology to help architects, archaeologists, and preservationists get better tools than tape measures and a clip boards and a pencils to go in and document these heritage sites.”
Hidden Mural Revealed
Sometimes new things are revealed during the scanning process. At Mission Dolores, CyArk worked hard to get behind the very ornately carved reredos, a false wall in back of the altar that was made in Mexico and shipped to the Mission by boat in 1796. For more than 200 years, the reredos has obscured a mural that was painted by the Indians when the mission was completed in 1791.
“There’s about a two foot space behind the frame where the statues are today,” says Andrew. “Very few have ever been able to see what’s behind. Using fiber optics they’ll be able to get a little pin wheel and be able to photograph. Then you’ll be able to click on say Saint Joachim with your smart phone and boom! You’ll be able to see behind, floor to ceiling, the mural that the Indians painted here at Mission Dolores.
“It’s not about the sites themselves,” says Barbara Kacyra, “It’s really about the stories. Whether it was Manzanar or Angor Wat, or Pompeii. It’s about the humanness of these sites.”
The History of San Francisco
There are almost 6000 Indians buried in the Mission Dolores cemetery, relates Andy Galvan, whose relationship to the Mission is much more than Museum Curator. Andrew is an Ohlone Indian whose ancestors were some of the first people baptized, married and buried at the Mission Dolores.
“If you walk around and look at the gravemarkers you’re going to read the history of San Francisco,” he says. “The 21 California missions are cultural heritage sites. These are our monuments. The Digital El Camino Real is about digitally imagining, about preservation. But it’s also about interpretation. It’s about what happened at the California Missions.”
