Australia: Maptek – a South African company is using I-Site 3D laser scanner to measure erosion of Apostles in Victoria, Australia. According to Wikipedia, twelve Apostles is a collection of limestone stacks off the shore of the Port Campbell National Park, by the Great Ocean Road in Victoria, Australia. Their proximity to one another has made the site a popular tourist attraction.
3D laser scanning will determine the degree of erosion by comparing annual scans to see whether there have been any changes to the weathered rock. This technology can be used from up to 2km away, so there is no need to navigate crumbling cliff tops, and it takes a panoramic photo at the same time.
“Public safety, I think, is the prime motivator but once you have that data it is part of the historical record and a permanent capture of exactly what’s there,” said James Moncrieff, Sales and Technical Consultant, Maptek.
The company is also surveying areas of the Californian coastline, where clifftop houses are “perilously close to the edge”, he said.
In August, the company used its Vulcan technology to help rescuers in the Chilean mine collapse decide where to drill to make contact with the 33 trapped miners and the orientation of the shaft used to retrieve them.
