In 2015, the Grange Cottages sluice and culvert were surveyed using two different methods, a high resolution laser scan and structure from motion photogrammetry. The majority of the site was surveyed using a Leica HDS6100 phase-based terrestrial laser scanner. 13 overlapping and intervisible laser scanner survey stations provided coverage of all surveyable areas. Panoramic digital photographs from each scan position and these images were used to texture the point cloud with photorealistic colour. The sluice gate was also surveyed using structure from motion photogrammetry. This technique uses multiple digital photographs from many angles to create a three-dimensional textured model.
