Exploring the distribution of dunes and the role of regional environmental differences in controlling dune development is a fundamental part of aeolian geomorphology research and has great significance for understanding the spatial variation of planetary surface processes and the associated environmental characteristics. The Mars Global Digital Dune Database (MGD3, https://www.usgs.gov/centers/astrogeology-science-center/science/mars-global-digital-dune-database ) has provided rich information on geographical structures to support research on the dune distribution on Mars.
