LiDAR to be used to reveal hidden Iron Age Archaeology

Bluesky laser survey, commissioned by the Morecambe Bay Partnership using LiDAR technology, is expected to reveal hidden archaeology of a Iron Age hill settlement at Lancashire, UK. Visually, the archaeological features are very difficult to see, but the Identified as an important ‘Heritage at Risk’ site, the site has already been subject to low level archaeological investigations, which have identified remains from a small, well defended hill fort.

“It is imperative that we get a better definition of the archaeological remains that are currently ‘hidden’ by the dense vegetation cover,” commented Louise Martin, H2H Cultural Heritage Officer at the Morecambe Bay Partnership. “This will enable us to develop conservation strategies for the site and work towards reducing the risk to the archaeological remains. The site is currently on Historic England’s ‘at risk’ register, so this work is crucial in developing partnerships and strategies to protect the monument for future generations.”

Morecambe Bay Partnership commissioned the Bluesky laser survey as part of the Heritage Lottery Funded Headlands to Headspace initiative, which is designed to improve the understanding of Morecambe Bay’s natural and cultural heritage and help conserve that heritage for future generations. The Bluesky LiDAR system uses lasers to accurately measure the earth’s terrain and record features on the ground in 3D. The dedicated survey plane is also equipped with aerial photography equipment, and will fly over the site during the winter months when the tree and canopy cover is at its minimum.

“Working with Bluesky, utilising their state of the art LiDAR system and proven experience in this field, we hope to reveal previously undiscovered details,” added Martin. “The laser equipment provides a fast and cost effective method of capturing highly accurate measurements of the entire site and its surroundings with minimum impact on a nationally important wildlife conservation site, a Site of Special Scientific Interest, in an Area of Outstanding Natural Beauty.”
