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...

SPARC-ing Geospatial Archaeological Research

The National Science Foundation has renewed its funding for the Spatial Archaeometry Research Collaborations (SPARC) Program, an initiative at the University of Arkansas that acts as a national hub for geospatial research in archaeology. The $277,264 grant allows the SPARC Program to continue to provide funding for data collection in the field and lab analysis, along with research expertise for archaeological research projects that use 3-D measurement, geospatial analysis and remote-sensing technologies. The SPARC Program helps researchers learn about spatial archaeometry, which measures properties of archaeological materials at all scales, including objects, sites and landscapes. The spatial properties of...

Modeling the Distant Past

Rachel Opitz, a research associate at the University of Arkansas’ Center for Advanced Spatial Technologies, is spending a large chunk of her summer at ancient ruins in the Mediterranean. CAST is collaborating with four ongoing projects that focus on the development of urbanism around the Mediterranean. These collaborations include teaching 3-D modeling and digital recording and survey techniques to field school students at Kalavasos – Ayios Dhimitrios in Cyprus and at Gabii in Italy and using terrestrial laser scanning at Vulci in Italy and Malthi in Greece. Laser scanning allows Opitz to collect and analyze billions of measurements which...

CAST: Capturing History in the Sweep of a Laser

Pictured above: CAST researchers Adam Barnes (from left), Katie Simon and Malcolm Williamson all participated in the documentary TV series Time Scanners. | Photo by Russell Cothren   Malcolm Williamson gingerly fastens the Leica ScanStation C10 to the top of a 5 ½ foot yellow tripod. He’s working in a computer lab down the hall from his office in the Center for Advanced Spatial Technologies at the University of Arkansas. “This is a survey-grade instrument and has to be handled as such,” says Williamson, one of the researchers at the center who use the laser scanner and other advanced remote...
