Sediment budget data for Lees Ferry dune field, February-May 2019

These data were compiled to enable estimation of aeolian dune field sediment budgets calculated using remote sensing methods. The objective of the study was to evaluate sediment budgets calculated for the Lees Ferry dune field in Grand Canyon, Earth as a terrestrial analog for aeolian dune fields in Valles Marineris, Mars. These data represent digital elevation models (DEM) of the topography of the Lees Ferry dune field in February and May, 2019, respectively. These data were collected with an Uncrewed Aerial Vehicle (UAV) remote sensing survey conducted on February 28th and then repeated on May 2nd, 2019. The images acquired with the UAV surveys were processed with photogrammetric modelling to produce the DEMs. These data were collected and processed by Geoff Debenedetto (USGS Arizona Water Science Center) and further processed and analyzed by Joshua Caster and Joel B. Sankey (USGS Southwest Biological Science Center, Grand Canyon Monitoring and Research Center). These data can be used to investigate the topography of, and calculate and evaluate remote sensing sediment budgets of, the Lees Ferry dune field.
