Identifying agricultural frontiers for modelling global cropland expansion - code and data

Code and data for Eigenbrod et al. "Identifying agricultural frontiers for modelling global cropland expansion " One Earth (2020) https://doi.org/10.1016/j.oneear.2020.09.006 . All code and data to re-create the analyses can be found in the 'Code and Input Data' folder'; the 'Frontierness_TIFFs' folder contains global geospatial files (TIFFS) of frontierness – calculated for both 1992 (as used in this paper) and for 2015 (latest data) .本数据集配套代码与数据源自Eigenbrod等人2020年发表于《One Earth（一个地球）》期刊的论文《面向全球农田扩张建模的农业边界识别（Identifying agricultural frontiers for modelling global cropland expansion）》，论文DOI链接为https://doi.org/10.1016/j.oneear.2020.09.006。用于复现该研究全部分析流程的完整代码与数据集，均可存放于「Code and Input Data（代码与输入数据集）」文件夹中；「Frontierness_TIFFs（边界度TIFF（Tagged Image File Format）文件）」文件夹内包含全球边界度（frontierness）地理空间文件，该数据分别基于1992年（即本文所用数据年份）与2015年（最新公开数据年份）计算得到。
