3D Digital Scanning at Trim Castle: OPW Archaeology Talk

On Thursday June 30th 2016, the OPW office in Trim will host a presentation on the current 3Dlaser scanning project at the National Monument sites of Trim Castle and the Black Friary, Trim, Co. Meath.

Professors Michael “Bodhi” Rogers of Ithaca College and Scott Stull of SUNY Cortland in cooperation with the OPW are conducting a 3D laser scan at these sites, using state-of-the-art scanning equipment.

The presentation will describe the results of this research and its application in advanced interpretation, conservation and preservation at the sites.

Rogers and Scott have collaborated on several projects combining archaeological excavation, geophysical archaeology, and 3D laser scanning including several landmarks in the United States, including Abraham Lincoln’s cottage in Washington D.C. and the Old Fort Johnson National Historic Landmark in Johnstown, New York.

The results will help inform future strategies for investigation, interpretation, and preservation at these sites, including on-line access to the archaeology through imagery generated by the scans, and advanced detailed recording techniques, preserving the site digitally for future generations.

“3D laser scanning is an emerging technology that facilitates digital preservation of standing structures,” said Rogers. “Our scanner pulses 50,000 times per second to take a reading every five millimeters. By moving the scanner around the site, we’ll create a full digital record that can be used to facilitate historic preservation planning, create virtual tours and aid in repairing any future damage to the structure.”

 “Our research at Trim Castle will be the largest historic structure we’ve laser scanned, which will provide us with interesting new challenges,” said Rogers.

Professors Stull and Rogers and the IAFS team will also collaboratively mentor students as they perform geophysical archaeological surveys and archaeological excavations at the Black Friary site.

The presentation will be on the 30th June 2016 at 6pm sharp in the Atrium in the OPW offices, Jonathan Swift Street, Trim, Co. Meath.
