Seeking tombs from space - Automatic detection and extraction of Omani burial monuments in satellite images.

There are thousands of burial monuments in the Sultanate of Oman. Despite some gaps in the cairn sequence, they are among the most consistent evidence of the human occupation between the third millennium B.C.E. and the seventh century C.E. For this reason, they have been used as a proxy for researching the ancient communities that inhabited these territories. Unfortunately, the majority of the extant studies have failed to develop comprehensive and systematic analyses of these tombs. The cause of the current situation is the absence of efficient methods to detect and record the burials. Traditional archaeological surveys cannot provide quantitative data for analysis of large areas. At the same time, the visual interpretation of satellite images is extremely time-consuming and cannot address the changes in archaeological data that have happened during the last decade. Recent developments in remote sensing have aimed to replicate the operation of visual interpretation automatically...Show moreThere are thousands of burial monuments in the Sultanate of Oman. Despite some gaps in the cairn sequence, they are among the most consistent evidence of the human occupation between the third millennium B.C.E. and the seventh century C.E. For this reason, they have been used as a proxy for researching the ancient communities that inhabited these territories. Unfortunately, the majority of the extant studies have failed to develop comprehensive and systematic analyses of these tombs. The cause of the current situation is the absence of efficient methods to detect and record the burials. Traditional archaeological surveys cannot provide quantitative data for analysis of large areas. At the same time, the visual interpretation of satellite images is extremely time-consuming and cannot address the changes in archaeological data that have happened during the last decade. Recent developments in remote sensing have aimed to replicate the operation of visual interpretation automatically using computer power. This application has the potential to overcome the issues of the current methodologies used for the detection of the burial monuments of Oman. This project aims to develop an efficient method to detect and record the burial monuments of Oman automatically. This approach allows for the limits of visual interpretation to be overcome and thus to fully exploit the quality and quantity of satellite images currently available. Furthermore, this thesis seeks to go beyond the simple detection of the burials, developing a process aimed at automatically digitalising the tombs. This will allow for the extraction of morphological information that, together with the geographical position of the remains, will allow for the burials to be dated. As a consequence, it will be possible to create rich datasets of tombs suitable for use in addressing current archaeological issues. Furthermore, the automation will also greatly assist in monitoring the status of the remains over time. This is necessary due to ongoing developments and looting activities that threaten the preservation of the tombs. The study and preservation of the burial monuments are indeed urgent issues for the archaeology of the Middle East.Show less
