Researchers from Griffith University 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 Journal of Computer Applications in ArchaeologyThe paper examines the use of lidar on the western Pacific island of Guåhan (Guam) to map locations that may not have been previously discovered.
Lidar (Light Detection and Ranging) is a non-invasive remote sensing technique that works by emitting 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 will be used to show what known archaeological sites look like on lidar so more archaeological sites can be found.
“Some of the sites are 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,” he said dr Jalandoni.
Victor H. Torres, an Indigenous archaeologist and mapping specialist, said the work is an interesting look at how modern technology like lidar can help discover and understand the past.
“In our project, we have shown an application of lidar data for Guåhan, but there are many other applications, such as sea level rise modeling or construction monitoring,” said Maria Kottermair, mapping specialist.
“We’ve only scratched the surface, and there’s a lot more that can be done with this technology.”
