The Wild Areas of the Northern Appalachian/Acadian ecoregion are those areas with a Human Footprint score equal to or less that 10 (HF <= 10). These are the 10% wildest, or least human influenced places in the ecoregion. The Human Footprint (HF) of the Northern Appalachian/Acadian ecoregion measures the extent and relative intensity of human influence on terrestrial ecosystems at a resolution of 90 m using best available data sets on human settlement (population density, dwelling density, urban areas), access (roads, rail lines), landscape transformation (landuse/landcover, dams, mines, watersheds), and electrical power infrastructure (utility corridors). The Human Footprint is calculated by assigning Human Influence...
The Future Human Footprint (FHF) of the Northern Appalachian/Acadian ecoregion projects the extent and relative intensity of human influence on terrestrial ecosystems over a 20-40 year span at a resolution of 90 m using best available data sets on human settlement (population density, dwelling density, urban areas), access (roads, rail lines), landscape transformation (landuse/landcover, dams, mines, watersheds), and electrical power infrastructure (utility corridors). The Future Human Footprint uses as a basis the Current Human Footprint, and projects forward salient, dynamic features of human infrastructure including residential roads, human settlement, and amenity development. It attempts to capture two dominant...
The Last of the Wild (LTW) of the Northern Appalachian/Acadian ecoregion are the 120 largest and wildest areas remaining in the ecoregion. The LTW are derived by taking the 10 largest areas in each ecological subregion (12) that have a Human Footprint score equal to or less than 10 (HF <= 10).The Human Footprint (HF) of the Northern Appalachian/Acadian ecoregion measures the extent and relative intensity of human influence on terrestrial ecosystems at a resolution of 90 m using best available data sets on human settlement (population density, dwelling density, urban areas), access (roads, rail lines), landscape transformation (landuse/landcover, dams, mines, watersheds), and electrical power infrastructure (utility...

The Human Footprint (HF) of the Northern Appalachian/Acadian ecoregion measures the extent and relative intensity of human influence on terrestrial ecosystems at a resolution of 90 m using best available data sets on human settlement (population density, dwelling density, urban areas), access (roads, rail lines), landscape transformation (landuse/landcover, dams, mines, watersheds), and electrical power infrastructure (utility corridors). Each 90m grid cell is attributed with a Human Footprint score between 0 and 100, where 0 represents minimum human influence and 100 represents maximum human influence at that location. The Human Footprint scores (0-100) may be interpreted as the percent influence. The Human Footprint...
The difference maps of the Future Human Footprint (FHF) and Current Human Footprint (CHF) of the Northern Appalachian/Acadian ecoregion portray the differences that may accumulate over time under each scenario. Please see metadata for the CHF and each FHF in order to understand how those layers are made. This difference map portrays the potential change over time - relative to the CHF - modeled by the "Current Trends" Future Human Footprint.The map is created by subtracting the current human footprint from the scenario modeled Future Human Footprint.
The Human Influence Index (HII) of the Northern Appalachian/Acadian ecoregion is a measure of direct human influence on terrestrial ecosystems at a resolution of 90 m using best available data sets on human settlement (population density, dwelling density, urban areas), access (roads, rail lines), landscape transformation (landuse/landcover, dams, mines, watersheds), and electrical power infrastructure (utility corridors). Each 90m grid cell is attributed with a Human Influence Index (HII) score plus the HI score of each input geographic data layer. HII scores are calculated by assigning Human Influence (HI) scores of 0 to 10 to geographic data layers that map features of human activity. Where 0 is no human influence...

Global spatial distribution and density of constructed impervious surface areas (ISA) in 2000-2001. The density of ISA for each grid cell is shown as a percentage of the total area. Examples of ISA include roads, parking lots, building, driveways, sidewalks and other manmade surfaces. The data was regridded and vectorized from the original raster version, which is available at: http://www.ngdc.noaa.gov/dmsp/download_global_isa.html.

The Last of the Wild Dataset of the Last of the Wild Project, Version 2, 2005 (LWP-2) is derived from the LWP-2 Human Footprint Dataset. The gridded data are classified according to their raster value (wild = 0-10; not wild >10). The ten largest polygons of more than 5 square kilometers within each biome by realm are selected and identified. The dataset is produced by the Wildlife Conservation Society (WCS) and the Columbia University Center for International Earth Science Information Network (CIESIN) and is available in the Geographic Coordinate system.
