Furthermore, drones can operate in diverse terrains, providing access to challenging or inaccessible locations, thereby broadening the scope of archaeological exploration ².

The application of drones in archaeology encompasses a wide array of technologies including high-resolution photo and video cameras, hyperspectral sensors, laser scanners, and thermal imagers ⁴. These tools facilitate a range of operations such as operational aerial photography, inspection, monitoring, recording, high-resolution imaging, and surveying objects in complex urban environments or enclosed spaces ⁴. Notably, drones equipped with photogrammetry software enable the creation of detailed three-dimensional models of sites, while lidar technology, exemplified by the DJI Zenmuse L1, can reveal objects concealed by vegetation, providing high levels of detail for mapping areas that are physically inaccessible for exploration ⁴⁶. The versatility of drones, capable of being used as a standalone solution or in conjunction with traditional surveying techniques, underscores their transformative impact on archaeological research ⁵.

Drones have also significantly advanced the methods of site preservation and cultural heritage conservation. By offering a non-invasive means of exploration, drones minimize the risk of unintended destruction and help preserve the integrity of the cultural landscape ². This technology captures imagery that reveals subtle variations in vegetation or soil conditions, indicating the presence of buried archaeological features, thereby aiding in the detection and documentation of new discoveries without the need for excavation ². The use of drones for photogrammetry flight missions takes efficiency and accuracy to a new level, enabling archaeologists to plan for future dig sites, assess damage to ancient sites from natural disasters or human activity, and assist in the digital reconstruction of ancient sites ⁴⁵. Through their ability to quickly cover large areas, access hard-to-reach locations, and capture high-resolution images and data, drones have become increasingly popular in archaeology and exploration, revolutionizing the way archaeological research is conducted and contributing to the preservation and conservation of cultural heritage ⁷.

Mapping Ancient Landscapes from Above

In the exploration of ancient landscapes, drones equipped with advanced technology have revolutionized the way archaeologists uncover and understand historical sites. Here are some of the key findings from recent drone surveys:
