Grid-mapping Hellas Planitia, Mars – Insights into distribution, evolution and geomorphology of (peri)-glacial, fluvial and lacustrine landforms in Mars' deepest basin

• Grid mapping provides valuable datasets for geographic and geostatistical analyses. • Gap of latitude-dependent mantle in NE Hellas probably caused by wind currents. • Scalloped terrain is controlled by solar insolation and aeolian activities. • Viscous-flow features and gullies are scarce at low elevations. • Even at high-resolution mapping, no clear shoreline morphologies have been discovere
