During WW1, combatants surveyed thousands of square kilometres, painstakingly mapping key locations into a now forgotten reference system. One hundred years later, the tMapper Team have harnessed the power of Google Maps to project a trench reference onto a modern map.
Advanced users can select multiple conversions, view elevation profiles, navigate to a location and search for nearby trench systems
