Titre : Typology shown by LiDAR of fossilized agrarian features and field systems under forest cover in Lorraine Auteurs : Murielle Georges-Leroy, Revue : Digital Archaeology Numéro : Issue 1 Volume : 4 Date : 2020/06/11 DOI : 10.21494/ISTE.OP.2020.0521 ISSN : 2515-7574 Résumé : Frequently highlighted by remote sensing airborne laser scanning, the agrarian features and field systems are preserved in the forest, in the form of microrelief, covering large areas. The range of forms in which they are shown raises the question as to their origin and their function. With the increasing number of lidarLiDAR surveys since the 2000’s the need to set up a framework for interpretation quickly became apparent. We propose here to present the typology of agrarian and field system remains preserved in the Lorraine forests based on a study consisting of four lidarLiDAR surveys over an area of about 300 km². A three-step approach to these remains has been developed: 1) identification of elementary forms, particularly those which are revealed by the visualization of lidarLiDAR data; 2) study of the morphogenesis of the remains, based on observations on the ground and some excavations enabling us to gain more insight into their features and their taphonomy; 3) morphological analysis of the field systems which contributes to the interpretation of some of these morphological features. This analysis is completed by a chronological approach. Éditeur : ISTE OpenScience
