  "description": "<p>This dataset contains a time series of very high-resolution dataset derived from UAV-generated images. Data covers the distal part of Zackenberg River, northeast Greenland. Images were captured using an unmanned aerial vehicle (UAV) immediately before (5<sup>th</sup> August 2017), during (6<sup>th</sup> August 2017), and after (8<sup>th</sup> August 2017) the glacier lake outburst flood.</p>\n\n<p>UAV-generated images were processed using the structure-from-motion approach in Agisoft Metashape software. Resultant products include digital elevation models, orthomosaics, and hillshade models. The second group of files (GIS_data.zip) contains vector files resultant from geomorphological mapping. &nbsp;</p>\n\n<p>Potential applications of the presented dataset include:</p>\n\n<ol>\n\t<li>&nbsp;assessment and quantification of landscape changes as an immediate result of glacier lake outburst flood;</li>\n\t<li>long-term monitoring of high-Arctic river valley development (in conjunction with other datasets);</li>\n\t<li>establishing a baseline for quantification of geomorphological impacts of future glacier lake outburst floods;</li>\n\t<li>assessment of geohazards related to bank erosion and debris flow development (hazards for research station infrastructure &ndash; station buildings and bridge);</li>\n\t<li>monitoring of permafrost degradation; and</li>\n\t<li>modelling flood impacts on river ecosystem, transport capacity, and channel stability.</li>\n</ol>\n\n<p>This dataset contains photogrammetric products derived from the UAV-generated images (orthomosaics, digital elevation models, hillshade models) and GIS products. Unprocessed images, which were the basis for structure-from-motion processing, can be accessed at: https://doi.org/10.5281/zenodo.4495282 (Tomczyk and Ewertowski, 2021)</p>\n\n<p>Tomczyk A.M., Ewertowski M.W., 2021: Before-, during-, and after-flood UAV-generated images of the distal part of Zackenberg river, northeast Greenland (August 2017), https://doi.org/10.5281/zenodo.4495282</p>",
