Pan (drag) the map & we find maps and overlay a Great War map (or aerial photo) over modern imagery.

• Our opacity slider lets you look at the modern landscape. Find the unmistakable scarring where faint chalk lines mark trenches in modern farmland. Marvel at the intricate detail & just how close the British & German front lines were.
• Use 'Find Maps' button (or 'Advanced Find') to locate a particular map. Zoom in and out & flick between satellite images, topographical maps or street maps. If you look at the aerial photos you can, in some cases, see a blockhouse, mine crater or preserved trench.
• Choose between France, Flanders, Gallipoli, Italy, Salonika & the UK.

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 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.
