Griffith University researchers are using the same technology that helps control automated vehicles and is used in speed cameras to find ancient sites in the Mariana Islands.
Published in the Journal of Computer Application in Archaeology, the paper explores the use of lidar on the western Pacific island of Guåhan (Guam) to map sites which previously may not have been discovered.
Lidar (Light detection and ranging) is a non-invasive remote sensing technique that works by sending out laser pulses and calculating the return time from surface reflections.
Dr. Andrea Jalandoni, a digital archaeologist from Griffith University’s Center for Social and Cultural Research, said the research was being used to showcase what known archaeological sites look like on lidar so that more archaeological sites can be found.
“Several of the sites are from the Latte, Spanish and Modern periods and we see that lidar is a very effective way to see and map the sites that are obscured and may not be visible due to vegetation,” Dr. Jalandoni said.
