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 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,...
