To provide a gridded version of existing vector maps of bird species distribution at 1- kilometer that preserves the original coding (1=Extant, 2= Possibly present, 3=Probably extinct, 4=Extinct, 5=Extirpated purposely, 6=Occurs on indicated island chain, and 7=Subfossil/fossil).

To provide provide information on the number of bird species present at a 1 kilometer spatial resolution which can be used in modeling efforts, wildlife conservation planning, natural resource management, policy-making, biodiversity studies and human-environment interactions.

To provide a database with observed responses to climate change for multidisciplinary studies.

To provide quantitative metrics for evaluating a country's environmental performance in different policy categories relative to clearly defined targets.

To provide an easily accessible, corrected EPA data set of the geo-referenced locations for all the National Priorities List sites in the United States and Puerto Rico.

To provide an easily accessible, corrected data set of polygons for hazardous waste sites in the United States which can be used to identify nearby populations and assess their potential risk.

To provide information on global land use for research on human-environment interactions.

To provide estimates of urban and rural populations and land areas in the low elevation coastal zone.

To make the acquisition, comparison and analysis of sustainability indicators easier by compiling them in a single database, incorporating multiple country codes, and condensing the indicator descriptions into short methodological summaries in an accompanying data dictionary.

To provide tabular data on environmental conditions (elevations, climate, coastal) in which people reside.

To provide geographical portraits of vulnerability designed to incorporate both exposure to climate change and national capacities to adapt.

To provide population estimates, gross domestic product, and surface area data to be used in conjunction with the sustainability indicators included in the compendium.

To serve a wide user community by providing composite Landsat images and raw data for urban areas that can be used in interdisciplinary studies of remote sensing and the environment.

To provide gridded demographic data, including characteristics of income, education, and housing, for metropolitan statistical areas at a finer resolution than is available in the 30 arc-second grids used for the United States as a whole.

To provide quantitative metrics for evaluating a country's environmental performance in different policy categories relative to clearly defined targets.

To provide gridded demographic data, including characteristics of age, race, ethnicity, and housing, for the United States and Puerto Rico for data integration.

To provide gridded demographic data, including characteristics of income, education, and housing, for the United States and Puerto Rico for data integration.

To help assess a country's demand on and supply of biological capital.

To provide gridded demographic data, including characteristics of age, race, ethnicity, and housing, for metropolitan statistical areas at a finer resolution than is available in the 30 arc-second grids used for the United States as a whole.

To provide an updated map of wild areas in Interrupted Goode Homosoline Projection which can be used for wildlife conservation planning, natural resource management, and research on human-environment interactions.
