The Global Human Footprint Dataset of the Last of the Wild Project,
Version 2, 2005 (LWP-2) is the Human Influence Index (HII) normalized by
biome and realm. The HII is a global dataset of 1-kilometer grid cells,
created from nine global data layers covering human population pressure
(population density), human land use and infrastructure (built-up areas,
nighttime lights, land use/land cover), and human access (coastlines,
roads, railroads, navigable rivers). The dataset is produced by the
Wildlife Conservation Society (WCS) and the Columbia University Center
for International Earth Science Information Network (CIESIN).
The
Human Footprint Index (HF) expressses as a percentagethe relative
human influence in each terrestrial biome. HF values range from
0 to 100. A value of zero represents the least influenced - the
"most wild" part of the biome with value of 100
representing the most influenced (least wild) part of the biome.
