“…The existing results indicate that the system able to reach centimeter‐level object accuracy. A similar concept was already utilized by other researchers, too (Bliakharskii et al, 2019; Eling et al, 2015; Hasheminasab et al, 2020).…”

“…As an intermediate platform of data collection, UAVs offer a flexible compromise between high spatial resolution and broad spatial coverage, therefore fill the gap between satellite observations and infield measurements [7]. Together with Structure-from-Motion (SfM) technique, they have demonstrated excellent performance even in harsh environmental conditions of polar regions, such as strong winds, low temperatures, weak illumination, geomagnetic anomaly [8]. On an appropriate scale, the applications of UAVs cover across multiple disciplines related to cold environments, such as albedo measurement [9], seaice characterization [10], navigation over polar ocean [11], snowpack property estimation [12], penguin counting [13] and vegetation ecology [14], etc.…”

“…There are extensive literature on UAV-based SfM or LiDAR applications in terrain morphological analysis. To guarantee the data quality, surveyors normally select ground control points (GCPs) from either existing topographic map [8] or in-situ measurements [30]. Alternatively, no GCPs geo-referencing approaches begin to emerge when conditions are limited [10], [31].…”

“…There are two traditional methods for the glacier surface modelling: space-borne remote sensing and ground-based measurements. With large spatial coverage, the space-borne satellite remote sensing cannot usually provide high resolution details for glacier surface mapping (Howat., 2019;Bliakharskii et al, 2019). For the ground-based measurements, the harsh weather and expensive logistics have greatly limited the reachability to the remote glacier regions, especially in Antarctica (Li et al, 2019).…”

“…To date, UAV has been employed in various aspects of cryosphere community, e.g., the topographic dataset (Benoit et al, 2019;Ewertowski et al, 2019) and the spatial distribution of ice cliffs and melt ponds on mountain glacier (Kraaijenbrink et al, 2016), supraglacial hydrological system of Greenland glaciers (Jouvet et al, 2018;Chudley et al, 2019), caving glacier monitoring in Greenland (Jouvet et al, 2019;Ryan et al, 2015), sea ice monitoring (Li et al, 2019), modelling of topography and forelands in Antarctica (Dąbski et al, 2020;Bliakharskii et al, 2019;Florinsky et al, 2019b). To date, however, compared with Greenland and High Asia regions, more detailed analysis should be performed for glacier surface micro-topography study in Antarctica that could be conducted by UAV technology.…”
