New Zealand's WWI tunnels in France uncovered by using laser scanning technology




The history of New Zealand's World War One underground tunnels in France has been uncovered by a group from Otago University, using laser scanning technology. 

The tunnels are a part of New Zealand's WWI history which has long been hidden underground.

In 1916, the New Zealand tunnelling company extended quarries below the town out to the German front line from where the allies launched a surprise attack. 

Richard Hemi from Otago University came up with the idea to capture the subterranean world using a laser that shoots points and measures where everything is, creating a 3D model video.

"As I looked into this story, I was surprised at how little people knew about Arras and these tunnels and to it was somewhat an untold story," he told 1 NEWS. 

"We do a scan that's maybe five to six minutes long and just scans everything in a 360 circle we then put the camera on which takes a panorama and puts colour of texture to the point cloud."

For nine weeks, the team worked underground alongside French students and lecturers to ensure the tunnellers legacy would be preserved.
