“…The simplest technique is Hill shading (HD), which consists of illuminating the relief, considered a Lambertian surface, with an artificial light source at given zenith and azimuth angles, thus providing the shape of the terrain in a realistic fashion (e.g., [10]).…”

Despite the recognized effectiveness of LiDAR in penetrating forest canopies, its capability for archaeological prospection can be strongly limited in areas covered by dense vegetation for the detection of subtle remains scattered over morphologically complex areas. In these cases, an important contribution to improve the identification of topographic variations of archaeological interest is provided by LiDAR-derived models (LDMs) based on relief visualization techniques. In this paper, diverse LDMs were applied to the medieval site of Torre Cisterna to the north of Melfi (Southern Italy), selected for this study because it is located on a hilly area with complex topography and thick vegetation cover. These conditions are common in several places of the Apennines in Southern Italy and prevented investigations during the 20th century. Diverse LDMs were used to obtain maximum information and to compare the performance of both subjective (through visual inspections) and objective (through their automatic classification) methods. To improve the discrimination/extraction capability of archaeological micro-relief, noise filtering was applied to Digital Terrain Model (DTM) before obtaining the LDMs. The automatic procedure allowed us to extract the most significant and typical features of a fortified settlement, such as the city walls and a tower castle. Other small, subtle features attributable to possible buried buildings of a habitation area have been identified by visual inspection of LDMs. Field surveys and in-situ inspections were carried out to verify the archaeological points of interest, microtopographical features, and landforms observed from the DTM-derived models, most of them automatically extracted. As a whole, the investigations allowed (i) the rediscovery of a fortified settlement from the 11th century and (ii) the detection of an unknown urban area abandoned in the Middle Ages.

“…Dans le domaine de l'archéologie, cette technologie a été employée pour la première fois en France dans la forêt de Haye pendant l'hiver 2006-2007(Georges-Leroy et al, 2011. Depuis, elle n'a cessé d'être utilisée par les archéologues, notamment pour sa capacité à traverser le manteau forestier et à faire abstraction du bruit atmosphérique (Bilodeau et al, 2008 ;Doneus et Briese, 2011 ;Georges-Leroy et al, 2011 ;Masini et al, 2011). L'acquisition des données LiDAR en forêt domaniale de Verdun a été réalisée par l'entreprise Sintégra, les 26 et 27 mars 2013 par envoi vers le sol d'impulsions laser depuis un avion situé à environ 600 m d'altitude.…”

Cent ans après la Grande Guerre, les traces des champs de bataille restent présentes dans les paysages du Nord-Est de la France. En 2013, une prospection par LiDAR aéroporté de la forêt domaniale de Verdun a mis en évidence sous forme d’images 3-D à haute résolution les vestiges de guerre masqués par le manteau forestier. Cette étude explore les potentialités de l’outil LiDAR pour l’analyse et la cartographie des témoins des aménagements militaires dans le bois des Caures (forêt domaniale de Verdun), lieu des premiers combats de la bataille de Verdun (1916). Le traitement d’images combiné à l’analyse de terrain permet d’établir une typologie et une cartographie inédites de la diversité des vestiges, abris et fossés, et de l’organisation du champ de bataille.

“…LiDAR, generally known as airborne laser scanning (ALS), is used by archaeologists to detect and map sites and to analyze past landscape since the last ten years (Cutchley and Crow, 2009;Masini et al, 2011;Georges-Leroy et al, 2014). Because of its ability to penetrate certain types of woodland canopy, this technology is a revolutionary tool for archaeologist interested in remains mostly located under forest areas which are still relatively unexplored.…”

International audienceThe use of Light Detection And Ranging (LiDAR) for archaeological purposes is becoming more prevalent in order to detect and to document remains located in forested areas. One of the main interests of airborne laser scanning is to put the archaeological information in their context, and to allow a better understanding of the relation between each item and its environment. This concept of archaeological landscape generally results in a too large amount of data to permit a manual analysis. This paper describes an approach for the automatic detection of elementary archaeological grazing structures, found in high concentration in some places of Auvergne (France). These elementary structures are generally connected, creating complex archaeological grazing sets. The detection process is based on the design of a model of an elementary grazing structure. The automatic detection is then carried out, based on the evaluation of the matching degree of each element with the model and on their belonging to complex archaeological grazing structures. The efficiency of the method is tested, by comparison with the manual digitalisation of an expert, on a restricted zone, and the results show that the success rate of the automatic detection reaches higher values than classical template matching approaches. The additional criterion, based on the belonging of each elementary structure to a more complex one, improves the detection success: In a complementary way, this approach offers new opportunities: it is also possible to detect complex structures with a template matching approach, if they contain some simple forms, that can be modelled
