Rebuilding Ancient Structures with Time Scanners

“It’s easy to get lost in the Colosseum,” said Adam Barnes, a researcher at the Center for Advanced Spatial Technologies at the University of Arkansas. And he knows the ancient structure better than most as part of a CAST research team that traveled to Rome to use the center’s cutting-edge remote sensing laser technology to build a 3-D perspective of a nearby similar amphitheater to find answers about the iconic structure’s past. CAST researchers are featured in the second season of Time Scanners, a three-part documentary series airing on PBS this month. Tonight’s episode features the Colosseum. On Dec. 23 the series shifts to...

Revealing the Secrets of Machu Picchu

Researchers in the Center for Advanced Spatial Technologies at the University of Arkansas have traveled around the world using their advanced remote sensing technology to provide a 3-D perspective of archaeological sites and historic structures. This month, PBS will air the second season of Time Scanners, a three-part documentary series featuring CAST experts using cutting-edge technology to reveal secrets about some of the world’s most iconic structures. Tonight’s episode focuses on the ancient mountain city of Machu Picchu in Peru. On Dec. 16 the series shifts to the Colosseum in Rome and Jerusalem on Dec. 23. All three shows are scheduled for...

A Virtual Museum

The University of Arkansas’ Center for Advanced Spatial Technologies has had a round of publicity lately. Previous blog posts by Chris Branam shared some behind-the-scenes tidbits of what researchers from CAST did during the production of Time Scanners, a three-part series that aired on PBS last month. CAST researchers were time scanners long before the series by that name. They scanned Native American artifacts for an Arkansas museum years ago. It is no Great Pyramids, but Hampson Archaeological State Park in Wilson, Ark. (half way between Memphis and Blytheville in the northeast part of the state) teamed up with...

Petra Behind the Scenes

The researchers at the Center for Advanced Spatial Technologies learned last year that a lot goes on behind the scenes during the making of a documentary television show. The third episode of Time Scanners, to be broadcast this evening nationally on PBS, took the CAST researchers to Jordan to scan the ancient desert city of Petra. They were filmed used their scanning techniques to explore how Nabatean stonemasons carved Petra’s largest building – the Monastery – out of a mountainside more than 2,000 years ago. The researchers also used ground-penetrating radar to discover what lies underneath the city. All...

Revealing Wren

Time Scanners, the new documentary series on PBS, shows University of Arkansas laser-scanning experts doing what they do best, using their advanced remote sensing technology to collect and analyze billions of measurements to form what is known as a point cloud, which provided a 3-D perspective of some of the world’s most iconic structures. This evening, St. Paul’s Cathedral in London is the focus of the scanning team in the university’s Center for Advanced Spatial Technologies. Sir Christopher Wren designed St. Paul’s in the 1670s, and his third design is embodied in the “Great Model” of 1673. The model,...
