Contained within this folder are shapefiles, and data tables derived from Hepburn et al 20XX




%%%%%%%%%%%%%%%%

SGLF_global.shp

ESRI standard shapefile format

The boundaries for all 320 superposed glacier-like forms (SGLFs) described in this study, all projected to the Mars2000 equicylindircal projection system.

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

ESRI standard shapefile

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).
