Point cloud data and visualisation of an englacial cut-and-closure channel on Austre Broggerbreen, Svalbard, in March 2016

The dataset encompasses the processed point clouds (.pts format), a panoramic tour, and a video flythrough of registered point clouds capturing a 122 m long reach of an englacial cut-and-closure channel in the glacier, Austre Broggerbreen, Svalbard, in March 2016. Point clouds were derived from 28 Terrestrial Laser Scanning (TLS) surveys, to characterise the morphology of the channel in three-dimensions and enable extraction of features reflective of hydrological flow conditions. The panoramic tour shows a greyscale image of the scan reflectivity values at each survey location, whereby the lighter the pixel colour, the greater the intensity of the laser beam return. This panoramic tour enables the viewer to self-navigate through the channel to see the morphological features within it. The video flythrough of the point cloud provides a visualisation of the point cloud data, travelling from the glacier surface, down the moulin and along the extent of the scanned reach. The point cloud has been coloured to reflect differences in height.
