    <description descriptionType="Abstract">&lt;p&gt;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&lt;sup&gt;th&lt;/sup&gt; August 2017), during (6&lt;sup&gt;th&lt;/sup&gt; August 2017), and after (8&lt;sup&gt;th&lt;/sup&gt; August 2017) the glacier lake outburst flood.&lt;/p&gt;

&lt;p&gt;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. &amp;nbsp;&lt;/p&gt;

&lt;p&gt;Potential applications of the presented dataset include:&lt;/p&gt;

&lt;ol&gt;
	&lt;li&gt;&amp;nbsp;assessment and quantification of landscape changes as an immediate result of glacier lake outburst flood;&lt;/li&gt;
	&lt;li&gt;long-term monitoring of high-Arctic river valley development (in conjunction with other datasets);&lt;/li&gt;
	&lt;li&gt;establishing a baseline for quantification of geomorphological impacts of future glacier lake outburst floods;&lt;/li&gt;
	&lt;li&gt;assessment of geohazards related to bank erosion and debris flow development (hazards for research station infrastructure &amp;ndash; station buildings and bridge);&lt;/li&gt;
	&lt;li&gt;monitoring of permafrost degradation; and&lt;/li&gt;
	&lt;li&gt;modelling flood impacts on river ecosystem, transport capacity, and channel stability.&lt;/li&gt;
&lt;/ol&gt;

&lt;p&gt;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)&lt;/p&gt;
