<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>
<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. </p>
<p>Potential applications of the presented dataset include:</p>
<ol>
<li> assessment and quantification of landscape changes as an immediate result of glacier lake outburst flood;</li>
<li>long-term monitoring of high-Arctic river valley development (in conjunction with other datasets);</li>
<li>establishing a baseline for quantification of geomorphological impacts of future glacier lake outburst floods;</li>
<li>assessment of geohazards related to bank erosion and debris flow development (hazards for research station infrastructure – station buildings and bridge);</li>
<li>monitoring of permafrost degradation; and</li>
<li>modelling flood impacts on river ecosystem, transport capacity, and channel stability.</li>
</ol>
