Frequent data collection is essential but often surveys can be costly and&amp;nbsp;time-consuming. Several costly and time-consuming tools and techniques have been developed during&amp;nbsp;the last few years for change detection and monitoring, allowing for both qualitative and quantitative&amp;nbsp;analysis. In this study we present the ability of an off-the-shelf Unmanned Aerial Systems (UAS)&amp;nbsp;coupled with Structure-from-Motion (SfM) photogrammetry to map and measure coastal features (e.g.&amp;nbsp;shorelines). The UAS surveys taken place over three campaigns during Autumn 2017 (November),&amp;nbsp;Spring 2018 (March) and Autumn 2018 (October) in Pinios river deltaic coast. The demonstrated&amp;nbsp;UAS-SfM methodology produced remote sensing data with great spatial resolution which could be&amp;nbsp;used to visually identify important parameters for coastal research and management at a fraction of the&lt;br&gt;cost of other available techniques and. Even an off-the-shelf UAS is suitable for repeat surveys to&amp;nbsp;assess spatial and temporal changes at small spatial extents and to better comprehend how these may&amp;nbsp;be related with site-specific natural processes along the coast.&lt;/p&gt;</style></abstract></record></records></xml>
