And finally… 3D digital model offers unique view of ancient Glasgow
Historic Environment Scotland (HES) has published a new 3D digital model of Fossil Grove in Glasgow, allowing users to explore the city’s ancient forest from a unique perspective.
The interactive model has been created through a combination of 3D laser scanning and photogrammetry. This process involves taking hundreds of overlapping images which are then combined to create a 3D model, enabling users to explore the site in detail from a range of different angles.
Fossil Grove, situated in Glasgow’s Victoria Park, is a Site of Special Scientific Interest comprising the spectacular fossilised remains of 11 Carboniferous Lycopod trees, which are around 325 million year old.
The site was discovered in 1887, and has been a popular visitor attraction from the Victorian era to the present day. Fossil Grove is the only site in the world where such trees have been preserved in their growth positions, and is considered one of the world’s first examples of geoconservation.
As well as allowing a new way to explore the site, the digital model will also play an important role in protecting Fossil Grove for the future. HES has been working with The Fossil Grove Trust and Scottish Natural Heritage (SNH) to ensure the long-term conservation of the fossils.
Sarah Hamilton, conservation scientist at HES, said: “Fossil Grove is a unique geological gem, and we’ve been working with partners over the past few years to support efforts to conserve and protect the site with the service and expertise of our Conservation Science and Digital Documentation teams.
“Recently, water penetration into the Victorian building that houses the fossils has caused discolouration and decay to some of the exhibits. We have undertaken 3D laser scanning and mineralogical analysis to help gain a better understanding of the site and these issues.
“As well as being a fantastic tool for interpretation, this new digital model is going to be of huge value to our work at Fossil Grove, as it’s allowing us to access even more detailed base information to create our risk map of the surface condition, which will help inform where we focus conservation efforts.”
Andy MacGregor, SNH operations officer, said: “This 3D modelling technology is bringing to life part of Scotland’s prehistory, hundreds of millions of years old. It is an invaluable way to understand our fascinating fossils, and conserve them for generations to come.”
