SGLF global boundaries

The boundary shapefile for all 320 superimposed 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).

本研究中描述的全部320个叠加类冰川地物（Superimposed Glacier-like Forms, SGLFs）的边界形状文件，所有文件均采用火星2000等圆柱投影系统进行投影。其中"Sinu_area"字段记录了通过对这些多边形采用正弦投影系统计算得到的每个SGLF的面积（单位：平方千米）。"Glob_ID"字段对应每个唯一的SGLF标识符，该标识符已在本仓库的table1.xlsx表格中列出。
