“…In a scientific context fostering the development of an unknown archaeological heritage (Desfossés, Jacques, & Prilaux, ; Robertshaw & Kenyon, ; Saunders, ; Van Hollebeeke, Stichelbaut, & Bourgeois, ), the use of lidar allows the measurement of both the extent and integrity of nonleveled battlefields at the landscape scale (Hesse, , ; Mlekuz, ). Several studies have simultaneously provided robust archaeological (Gheyle et al., ; Saey, Stichelbaut, Bourgeois, Van Eetvelde, & Van Meirvenne, ; Stichelbaut et al., ) and environmental models (Bausinger, Bonnaire, & Preuß, ; Hupy & Kœlher, ; Hupy & Schaetzl, ), highlighting the extreme impact of 20th century global conflicts on the landscape (Schnitzler, Landolt, Jacquemot, Legendre, & Laparra, ), in particular that of the Western Front in the WW1, where millions of soldiers lived, fought, and were compressed along a front line extending over 700 km.…”
