Last of the Wild Project, Version 3 (LWP-3): 1993 Human Footprint, 2018 Release

The 1993 Human Footprint, 2018 Release provides a global map of the cumulative human pressure on the environment in 1993, at a spatial resolution of ~1 km. The human pressure is measured using eight variables including built-up environments, population density, electric power infrastructure, crop lands, pasture lands, roads, railways, and navigable waterways. The 1993 Human Footprint was developed to allow inter-comparability with the 2009 Human Footprint. The data set is produced by Venter et.al., and is available in the Mollweide projection.2018年发布版1993年人类足迹数据集（Human Footprint）提供了1993年全球环境累积人类压力的空间分布图，空间分辨率约为1千米。该人类压力指标通过八大变量进行测算，涵盖建成环境、人口密度、电力基础设施、耕地、牧草地、道路、铁路及通航水道。本数据集的构建旨在与2009年版人类足迹数据集实现跨版本可比对。本数据集由文特（Venter）等人编制，采用摩尔魏特投影（Mollweide Projection）格式发布。
