The Human Influence Index Graphics

The Human Influence Index, from the Last of the Wild data set, is a measure of direct human influence on terrestrial ecosystems using the best available data sets on human settlement (population density, built-up areas), access (roads, railroads, navigable rivers, coastline), landscape transformation (land use/land cover) and electric power infrastructure (nighttime lights). Its values range from zero to 64, with zero representing no human influence and 64 representing maximum human influence.
