As part of the framework for the Archaedyn project, this work aims to understand spatial discontinuities in ancient land use through the analysis of ancient agrarian structures preserved by forest cover in Lorraine and Burgundy, northeast France. The first step consisted of examining the intensity of landuse (the density of linear features, stone piles, and the mean length of features) and its structuring (degree of closure, shape and surface area of field parcels) indicators. The second step consists of spatially analysing these parameters in order to identify homogeneous zones. These zones will then be compared to environmental and human factors in an attempt to understand how these field systems were established.
