The field 'Sinu_area' lists the area (km^2) of each SGLF derived from a sinusoidal projection system of these polygons. The field 'Glob_ID' refers to each unique SGLF idea, as listed in table1.xlsx (this repository). %%%%%%%%%%%%%%%% Craters.shp Shapefile describing the diameter of all craters mapped in this study, on both SGLFs and their underlying VFFs. Projection system is 'SimpleCylindrical_Mars' %%%%%%%%%%%%%%%% Data_file_S1.xlsx Excel file listing the inventory of SGLFs and their morphometric characteristics %%%%%%%%%%%%%%%% Data_File_S2.xlsx Excel file listing the counting area and crater counts in different crater diameter bins on each SGLF aggregate (Sheet 1) and its underlying VFF (Sheet 2).
