This dataset is a pointcloud over Almaty city, Kazakhstan, derived from Pleiades tristereo optical imagery acquired in 2017. Both the pointcloud were produced using Agisoft Metashape (version 1.6.2). The raw imagery was 0.5m resolution Pleiades tristereo imagery, which was processed in Agisoft with ‘High’ accuracy alignment parameters, and the depth maps were produced using ‘Ultra high’ quality and ‘Mild’ filtering. This has been co-registered to TanDEM-X following the geolocation procedure of Nuth et al 2011, which shifted this pointcloud by 0.08/0.72/0.80 metres in the x/y/z directions respectively.

A complete description of the generation of 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. Please cite this publication if you use this dataset:
