What is Lidar?

The Arfordir Penfro portal has been developed to help increase our understanding of known and unknown archaeology and improve management of these in the northern section of the National Park. The portal utilises high resolution Lidar that was collected and funded as part of the Welsh Government and European Union’s Sustainable Management Scheme project known as ‘Dawnsio ar y Dibyn’.

You can digitally remove surface data to reveal long-forgotten archaeology sites. This helps us to better understand and conserve the historic landscape.
