Survey of the 2008 Nura earthquake surface rupture, Kyrgyzstan, 2018

Published by OpenTopography | OpenTopography | Catalog Last Checked: August 01, 2026 at 03:00 AM | Dataset Last Updated: March 05, 2024
This raster is related to the surface rupture resulting from the 2008 Nura earthquake in south Kyrgyzstan. Digital surface models (DSM) were generated by acquiring low-altitude (between 35–120 m) aerial photographs using an unmanned aerial vehicle (UAV). UAV drone models included the DJI Phantom 4 Pro and Mavic Pro carrying cameras with build in global navigation satellite system (GNSS) with 10 m accuracy, and a photo pixel resolution of 5472 x 3648 px and 4000 x 3000 px, respectively. To reduce the positional error of the resulting models, ground-control points (GCP) were placed throughout the survey areas with ~DIN-A0-sized blue tarp targets. The target positions were measured using a kinematic differential GNSS (dGNSS) system. The dataset comprises eight individual sets, each subdivided into four tiles. This segmentation is necessitated by the substantial size of the dataset, a result of its high resolution. This high resolution enables the precise resolution of surface rupture offsets down to the decimeter scale.
