American Vegetation/Land Cover Classification and Conservation
Status This report assesses the degree to which both existing and proposed terrestrial protected area networks protect/would protect landscape-level biodiversity, which we represent as vegetation types delineated from remotely-sensed imagery. A comprehensive, standardized, and thematically appropriate map of [Central-American] vegetation and landcover types was developed by classifying AVHRR imagery (advanced very high resolution radiometer imagery—1 km2 resolution) using advanced digital image processing routines and expertise provided by a Central America Vegetation Working Group. The map identifies 17 remaining natural vegetation types. The classification accuracy of the map is estimated to exceed 80%. __________________________________________________________________________________________________________________________________________________________________________ |

Dimensions Data Collection This collection includes a variety of socioeconomic data, such as county-level geographic information system (GIS) databases, presented at a scale of 1:1,000,000. __________________________________________________________________________________________________________________________________________________________________________ |
| Georeferenced
Population Data Sets of Mexico The Georeferenced Population Data Sets of Mexico consists of the following products: Population Database of Mexico; Urban Place, Time-Series Population Spreadsheet of Mexico; Urban Place GIS Coverage of Mexico; GIS Coverage of Mexican Localities; GIS Coverage of Mexican States; GIS Coverage of Mexican Municipalities; Raster Based GIS Coverage of Mexican Population; and GIS of Mexican states, municipalities, and islands. __________________________________________________________________________________________________________________________________________________________________________ |
| Global Rural-Urban Mapping Project (GRUMP)—alpha version The Global Rural-Urban Mapping Project (GRUMP) provides a new suite of data products that add urban-rural specification to the Gridded Population of the World (see below). This project was developed out of a need for researchers to be able to distinguish population spatially by urban and rural areas. The central data product resulting from GRUMP is called Gridded Population of the World with Urban Reallocation (GPW-UR) on a 1km grid. Additional datasets resulting from GRUMP include a land area grid showing urban areal extents worldwide and a database of human settlements, their spatial coordinates, and populations. __________________________________________________________________________________________________________________________________________________________________________ |

Gridded
Population of the World (GPW)—version 3 Gridded Population of the World (GPW v3) is the third edition of a large-scale data product that demonstrates the spatial distribution of human populations across the globe. The purpose of the GPWv3 project is to provide a spatially disaggregated population layer that is compatible with datasets from social, economic, and earth science fields. The output is unique in that the distribution of human population is converted from national or subnational spatial units (usually administrative units) of varying resolutions, to a series of geo-referenced quadrilateral grids at a resolution of 2.5 arc minutes (~20 sq. km area at the equator). The data set provides estimates of the population of the world in 1995 and 2000, both population counts (raw counts) and population densities (per square km). _________________________________________________________________________________________________________________________________________________________________________ |
Human Appropriation of Net Primary Productivity (HANPP) |
| Human Footprint Data Set This data set analyzes the geographic extent of human impacts on the environment. The analysis indicates that 83% of the earth's land surface is influenced directly by human beings, whether through human land uses, human access from roads, railways or major rivers, electrical infrastructure (indicated by lights detected at night), or direct occupancy by human beings at densities above 1 person per square kilometer. The “Human Footprint” data set is available in Band Interleaf (BIL) format. _________________________________________________________________________________________________________________________________________________________________________ |
Laguna Merin Data Collection |
| Last of the Wild Data Set This data set was created to facilitate policy making aimed at conserving the last of the world's wild areas—those areas least influenced by human activities. From this website you can download the “Last of the Wild” data set in BIL and ArcInfo Exchange (.e00) formats. _________________________________________________________________________________________________________________________________________________________________________ |
| Low Elevation Coastal Zone Urban-Rural Estimates Country-level estimates were generated globally using Global Rural-Urban Mapping Project (GRUMP) alpha population and land area data products and a Digital Elevation Model (DEM) derived from Shuttle Radar Topographic Mission (SRTM) remote sensing data. The zone was derived from the DEM by selecting all land contiguous with the coast that was 10 meters or less in elevation. All grids (population, land area, urban mask and LECZ) are at 1 km (30 arc-second) resolution. _________________________________________________________________________________________________________________________________________________________________________ |

| U.S. Census Grids Comprised of gridded data sets for a wide variety of demographic and socioeconomic characteristics of individuals, households, and housing units. The data are available at 30 arc-second resolution for the continental United States, the 50 states, the District of Columbia, and Puerto Rico; and at 7.5 arc-second resolution for the 50 largest metropolitan statistical areas. __________________________________________________________________________________________________________________________________________________________________________ |
| U.S. PUMA
Boundary Files The PUMA (Public Use Microdata Sample Areas) boundary files consist of a 5% sample (apuma) and 1% sample (bpuma) areas for the mapping of 1990 PUMS (Public Use Microdata Samples) data covering the continental United States, Alaska, and Hawaii. These boundary files were created based on equivalency files generated by "Geocorr," the geographic correspondence engine. A national census tract to PUMA geography correspondence file was used in merging the two files resulting in the PUMA geographies. An additional file is also available consisting of geographic centroids for the PUMA coverages calculated by UIC (Urban Information Center/ Office of Computing, University of Missouri). ___________________________________________________________________________________________________________________________________________________________________________ |

Archive of Census-Related Products This FTP archive is a collection of georeferenced data files containing census information that spans the United States. It is comprised of boundary, standard extract, zip equivalency extract, enhanced migration, street intersection,and census block statistics files. Documentation describing the data and filename convention has been included, as well as programs to facilitate format conversion and platform portability. These data are value-added products derived from original census files compiled and distributed by the U.S. Bureau of the Census. ____________________________________________________________________________________________________________________________________________________________________________ |

Population, Landscape, and Climate Estimates (PLACE) The PLACE data set provides,
in tabular format (Excel or CSV), estimates of national-level
aggregations for the following thematic areas: 1) biome; 2) climate;
3) coastal proximity; 4) elevation; and 5) population density.
It permits easy comparisons across countries on such measures
as the number of persons living within 100 kilometers of a coast,
the percent of territory above 2,000 meters, and the number of
persons living within different climatic zones. |
