2020 winter timeseries of UAS derived digital surface models (DSMs) from the Hourglass study site, Bridger Mountains, Montana, USA
Unmanned Aerial System (UAS) flights were conducted over the headwaters of the South Fork of Brackett Creek in the Bridger Mountains of SW Montana during the winter of 2020. The flights collected overlapping imagery focused on a steep mountain couloir study site known locally as "the Hourglass." Structure from motion (SfM) photogrammetry was used to process the collected imagery and create digital surface models (DSMs) of the landscape on 13 field days. The data was collected between January 7, 2020 and July 8, 2020 and includes 12 snow-on models as well as 1 snow-free model. The snow-on DSMs represent snow depths calculated using DSM-differencing techniques (subtraction of snow-free surface from snow-on surface). Other files include a shapefile of study locations and csv files of data used in analyses described in the associated manuscript.
