Khalifa University’s Lab Uses Remote Sensing Observations To Find Potential Unexplored Archeological Sites In UAE

ABU DHABI, (UrduPoint / Pakistan Point News / WAM - 27th Jul, 2021) Khalifa University of Science and Technology has announced that researchers at its Environmental and Geophysical Sciences (ENGEOS) Lab have used satellite remote sensing observations to detect buried objects in already known archaeological sites and to identify potentially unexplored archaeological sites in the UAE by applying machine learning techniques to satellite data.
The novel method, which combines satellite data and machine learning, was developed at Khalifa University and can be applied to similar desert environments in the UAE and elsewhere. With this technology, the researchers were able to find a new potential area, unexplored yet by classic methods. This area is buried under the ground and is located on the opposite side of the current excavations.
Currently, the ENGEOS Lab at Khalifa University is investigating another archaeological site near Al Ain in the UAE.
Results from the ENGEOS research project led by Dr. Diana Francis, head of ENGEOS Lab, show that radar imaging allows direct detection and characterization of known as well as potentially novel buried archaeological sites. Researchers use satellite-borne Synthetic Aperture Radar (SAR) at very high resolution that can detect features of the size of one meter that might be buried in the subsurface (less than two meters) under optimum conditions, that is, dry and bare soils such as the soil at Saruq Al Hadid site. Moreover, remotely sensed data are well-suited for supporting regional archaeology, as well as tracking of environmental factors that influence archaeology.
Based on the machine learning techniques and deep learning analyses conducted during this work, the ENGEOS Lab was able to find potential areas for further on-site investigation. The unsupervised artificial intelligence developed during this project was partially validated as it was able to find the areas already under excavation on the site. As a next step, the method developed during this first phase of the project will need to be validated through a field survey, which will help improve the accuracy of the results.
This technology will not only help reduce the cost of archaeological exploration but will also effectively help archaeologists identify potential locations. At the same, it will create a model that will be more accurate with time, because it has the ability to learn and use this knowledge.
Dr. Arif Sultan Al Hammadi, Executive Vice-President, Khalifa University of Science and Technology, said, "Khalifa University researchers focus their efforts not only on science, engineering, technology and healthcare areas, but also are able to apply remote sensing to archaeology to explore UAE’s cultural and heritage sites. The ENGEOS Lab leads remote sensing at Khalifa University and has developed an archaeology application with the potential to be applied to similar desert environments, anywhere in the world."
The Saruq Al Hadid archaeological site was selected for the first study by the ENGEOS researchers. This site had earlier been investigated by a team of researchers from Dubai Municipality and the Mohammed bin Rashid Space Center (MBRSC) Lab, indicating the presence of buried settlements in the site used by ancient indigenous workers.
Discovered in 2002, Saruq Al Hadid sits deep in the desert of the southern reaches of Dubai emirate and is believed to have been an iron-age metal ‘factory’ in operation around 1,300-800 BC. Even though relics from the Stone Age (10,000 BC) have also been discovered, the peak period of the site is believed to have been around 3,000 BC. Based on up to 12,000 artefacts found on the site, archaeologists believe it is one of the main centers of copper tool manufacturing in the region since the beginning of the Iron Age (1,000 BC).
Dr. Francis said, "Remote sensing has been able to assist archaeological research in several ways in recent years, including detection of subsurface remains, monitoring of archaeological sites and monuments, and archeo-landscapes studies. Now, artificial intelligence and machine learning applied to remote sensing can provide additional support and invaluable guidance for on-site archaeological work.
