“…Nowadays, SfM photogrammetry paired with multi-view stereo (MVS), hereafter together referred to as SfM, represents a powerful and successful tool to produce high-quality three-dimensional (3D) surfaces for geoscience applications. In literature, several researches have used this technology to carry-out different kinds of analysis and studies on: structural geology (e.g., Bemis et al, 2014); debris-flow dynamics (Cucchiaro et al, 2019); surveying submerged surfaces (e.g., Woodget et al, 2015;Dietrich 2017); soil erosion (Glendell et al, 2017); design of drainage network (Pijl et al, 2019) or agricultural terraces 3D reconstruction (Pijl et al, 2020); gullies and badlands (e.g., Stöcker et al, 2015;Smith and Vericat 2015;Koci et al, 2017); fluvial morphology (e.g., Javernick et al, 2014;Marteau et al, 2017) and aquatic applications (Carrivick and Smith 2018); glaciers (e.g., Immerzeel et al, 2014;Piermattei et al, 2015;Mallalieu et al, 2017); monitoring on landslide displacement (e.g., Stumpf et al, 2015;Clapuyt et al, 2017;Eker et al, 2018;Turner et al, 2015); coastal recession (e.g., James and Robson 2012;Westoby et al, 2012); open-pit mining areas (Chen et al, 2015;Xiang et al, 2018); extraction of biophysical forest or plants parameters and monitoring (e.g., Iglhaut et al, 2019;Malambo et al, 2018;Zarco-Tejada et al, 2014). Moreover, studies are shifting from proofof-concepts in topographic survey to genuine applications including quantification of bathymetric surveys, underwater archaeology, grain-size mapping, restoration monitoring, habitat classification, geomorphological change detection and sediment transport path delineation (Carrivick and Smith 2018).…”
