From the air to beneath the soil – revealing and mapping great war trenches at Ploegsteert (Comines‐Warneton), Belgium

Recent military battlefield sites are often recorded by accident during geophysical investigations researching into earlier archaeological landscapes. The First World War (Great War) perhaps left its traces like no other war before or since in Europe. For the first time, a large area, some 16 ha in extent, has been surveyed over a modern conflict landscape. The authors have attempted to combine two remote sensing techniques: analysis of contemporary Great War aerial photographs and geophysical prospection techniques. The combination of two different approaches leads to a more comprehensive understanding of the Great War battlefield and an understanding of the value of remote sensing in this new area of applied research.
