Global terrestrial Human Footprint maps for Alaska, 1993 and 2009, with SASAP regional subsetting

Human Footprint data was extracted for thirteen regions of Alaska for years 1993 and 2009 for the State of Alaska Salmon and People (SASAP) project. Methods and code for the regional extraction can be found in "HumanFootprint.ipynb" in this package. Human Footprint data is based on an original dataset "Global terrestrial Human Footprint maps for 1993 and 2009" acquired here https://doi.org/10.1038/sdata.2016.67, by Venter O, Sanderson EW, Magrach A, Allan JR, Beher J, Jones KR, Possingham HP, Laurance WF, Wood P, Fekete BM, Levy MA, Watson JE (2016). The Human Footprint index is based on remotely-sensed and bottom-up survey information on eight variables: 1) built environments, 2) population density, 3) electric infrastructure, 4) crop lands, 5) pasture lands, 6) roads, 7) railways, and 8) navigable waterways. Original data is distributed by the Dryad Digital Repository (https://doi.org/10.5061/dryad.052q5.2).

本数据集为阿拉斯加三文鱼与人类项目（State of Alaska Salmon and People, SASAP）提取了1993年与2009年阿拉斯加13个区域的人类足迹（Human Footprint）数据。区域提取的方法与代码可在本数据包的"HumanFootprint.ipynb"文件中获取。人类足迹数据的原始来源为Venter O等人2016年发布的《1993年与2009年全球陆地人类足迹地图》，获取链接为https://doi.org/10.1038/sdata.2016.67，作者包括Venter O、Sanderson EW、Magrach A、Allan JR、Beher J、Jones KR、Possingham HP、Laurance WF、Wood P、Fekete BM、Levy MA、Watson JE。人类足迹指数基于8类遥感与自下而上调查获取的变量：1）建成环境，2）人口密度，3）电力基础设施，4）耕地，5）牧场，6）道路，7）铁路，8）通航水道。原始数据由Dryad数字知识库（Dryad Digital Repository）发布，链接为https://doi.org/10.5061/dryad.052q5.2。在现有法律允许的范围内，作者已放弃该数据的全部版权及相关或邻接权利。
