La forêt de Haye se situe à l’ouest de Nancy, en Meurthe-et-Moselle (54). Il s’agit d’un massif de 11600 ha qui a fait l’objet de nombreuses études associant la DRAC Lorraine, l’ONF et INRA.
The TRAIL international meeting took place from March 26 to 28 in Frasne (Doubs, France). It was dedicated to LiDAR (Light Detection And Ranging) datas study under forest covered spaces. The LiDAR technology allows generating high precision altimeter models from the floor no matter the vegetal cover. These models had been highly multiplicated for the last five years, in the European area, delivering an important quantity of new archeological discoveries under plants covers. Since 2009, the Franche-Comté region is one of the most emblematics study casesof the European network Archaeolandscape, thanks to a Lidar data acquisition with high precision (8 points / m2) funded by the Region and the development of an integrated methodology for detection and archaeological survey.
