Beginning in 2005, volunteers from The Western Front Association scanned maps, photos & sketches from the Imperial War Museums. We supported them with a significant donation.

With 10,000 items scanned, we use the latest digital technology to georeference as many as possible - and for a small fee download. Members can download a number of these free every month.

Convert a Great War trench map reference to a modern location. Use Street View to see the battlefields from ground level. Measure distance & bearing.

Some maps may appear to be slightly misaligned, but overlaying historic maps produced long ago in trying conditions in an obscure projection with different cartographic techniques is an art. It is surprising how many roads, rivers, canals & railways still exist & exactly align. Where they do not, tempting as it is to believe that the feature has changed, but the most likely reason is that it is just not possible to line up every single hand-drawn historic feature & show it on computer-generated satellite-imagery without some distortion.
