International audienceThe LiDAR (Light Detection and Ranging) technique allows a very fine restitution of the topography from a laser scanner on board an aircraft. For several years now, this technology has been making archaeological remains visible over square kilometers of forest areas that were previously invisible from the sky. The archaeological sites are reconstructed with their environment (roads, plots of land, agrarian structures, etc.) at scales that were previously difficult to analyze. This special issue provides us with an overview of French approaches to the archaeological exploitation of LiDAR without claiming, far from it, to be exhaustive, as there is so much work to be done, both in France and abroad. However, the range of...
