The pointcloud was produced using Agisoft Metashape (version 1.6.2). The raw imagery was 0.5m resolution Pleiades tristereo imagery, which was processed in Agisoft with \u0091High\u0092 accuracy alignment parameters, and the depth maps were produced using \u0091Ultra high\u0092 quality and \u0091Mild\u0092 filtering.  The original 202,403 tiepoints were filtered down to 153,326 before creation of the dense clouds by removing tie-points with a projection accuracy of greater than 5. The image has been cropped slightly at the edges to remove edge artefacts.\n\nMore information about this dataset, the images that were used to construct the pointcloud and how the co-registration was performed can be found in the associated manuscript:\n\nAmey RMJ, Elliott J, Watson C, Walker R, Pagani M, Silva V, Hussain E, Abdrakhmatov K, Baikulov S, Tilek kyzy G, Improving urban seismic risk estimates for Bishkek, Kyrgyzstan, from improved geological knowledge of hazards, submitted 2021\n\nThis work has been supported by the the Royal Society GCRF Challenge grant (CHG\\R1\\170038) and the NERC Innovation award (grant number NE/S013911/1).
