The Knockando Woolmill in Morayshire has been in continuous operation since the 18th century and is one of the last remaining mills of its kind in Scotland and indeed, the world. The mill is currently undergoing an extensive programme of conservation and restoration. In advance of these works, TCG, in collaboration with colleagues at the Digital Design Studio, Glasgow School of Art and RCAHMS spent four days in July 2009 digitally documenting the site in its entirety in 3D – from buildings and surrounding landscape, to mill and cottage interiors and even intricate 19th century machinery.
Documentation involved the use of 3D terrestrial laser scanners and advanced GPS survey equipment. The data acquired will be used in several ways by both the Woolmill Trust and by visitors to the site. Sophisticated 3D animations will be generated to enhance visitor understanding of the woolmill and provide virtual access for those unable to visit in person. Highly accurate measurements can be made from the laser scan ‘point cloud’ data. In terms of the conservation work, such measurements of machinery components and the measurement of machine positioning within the mill buildings will inform the dismantling and later re-instatement in their original locations in the renovated buildings. Architectural drawings can also be produced from the point cloud data to further understanding of the historic structures.
