LiDARRAS surveying project

Under the French city of Arras, New Zealand and French surveyors are using laser scanning technology to capture, honour, and preserve the incredible work of the NZ Engineers Tunnelling Company. 

Large 'Kia Ora' carving left by the New Zealand Engineers Tunnelling Company in the Blenheim quarry underneath Arras, France.

Under the northern French city of Arras, there is a network of caves and tunnels that hold huge significance for New Zealanders. They represent a permanent but unseen memorial to the brave and industrious actions of the New Zealand Engineers Tunnelling Company during the First World War.
Surveyors from Otago’s National School of Surveying along with counterparts from the École Supérieure des Géomètres et Topographes (ESGT Le Mans, France) are working together using 3D laser scanning to document, honour, and preserve the story and incredible work of the men from the NZETC. The 3D record of tunnels and caves will provide a stunning virtual world to be explored from the safety of their website.
