This project aimed to uncover evidence of pirate presence from the 17th and 18th centuries on Sainte-Marie Island, Madagascar. Led by renowned archaeologist Jean Soulat and supported by the “Archéologie de la Piraterie” association, it sought to illuminate the lives of buccaneers both at sea and on land. The island, known for its dense tropical vegetation and rugged terrain, required innovative surveying techniques to reveal hidden structures.

AIRD’ECO-Drone was tasked with mapping approximately 100 hectares around Ambodifotatra Bay. Utilizing UAV-mounted LiDAR systems, the team generated high-resolution DTMs to identify traces of pirate habitation, such as dwellings, walls, and freshwater supply structures. This geospatial data was overlaid with historical maps, offering a detailed understanding of pirate life and land use.

Key findings included the identification of a freshwater inlet dam, presumed to be a critical resource for pirates, and bastions within Fort de la Possession, likely remnants of defensive structures. The discovery of remote dwellings inaccessible on foot further demonstrated the effectiveness of UAV technology in archaeological research.
