Almaty city, Kazakhstan, 2014 (derived from Pleiades stereo imagery)

This dataset is a Pointcloud over Almaty city, Kazakhstan, derived from Pleiades stereo panchromatic optical imagery acquired in 2014. The four scenes (two pairs, covering different but overlapping areas) were processed in Agisoft Metashape version 1.6.2 with ‘High’ accuracy alignment parameters, and the depth maps were produced using ‘Ultra high’ quality and ‘Mild’ filtering. These have been co-registered to TanDEM-X following the geolocation procedure of Nuth et al 2011, which shifted the eastern pointcloud by 1.61/2.24/-5.76 metres in the x/y/z directions respectively, and the western pointcloud by 3.06/1.50/-2.79 metres in x/y/z respectively. A complete description of the generation of these datasets, the images that were used to construct the DEMs and the co-registration can be found in the associated paper.
