Last Updated on 25th April 2022

ZEB1 featured on BBC’s ‘Coast’ series, used to map Brei Holm, a dangerous cave in Papa Stour, one of the Shetland Islands in Scotland.

The episode featured Andy Torbet with laser survey specialist Kevin Dixon and the help of boat operator Ryan Leith, using the hand held scanner to make history, mapping some of the most impressive sea caves in Britain.




When examining the data, the researchers were impressed with the quality of the point cloud, noting the details such as a hole in the roof being documented to superb accuracy.

Andy Torbet said: ‘Surveys like this could be used to predict cave and tunnel collapse, saving lives and transforming coastal management’.
