Gridded Population of the World, Version 4 (GPWv4): Population Density, Revision 10

Center For International Earth Science Information Network-CIESIN-Columbia University
The Gridded Population of the World, Version 4 (GPWv4): Population Density, Revision 10 consists of estimates of human population density based on counts consistent with national censuses and population registers, for the years 2000, 2005, 2010, 2015, and 2020. A proportional allocation gridding algorithm, utilizing approximately 12.5 million national and sub-national administrative units, is used to assign population values to 30 arc-second (~1 km) grid cells. The population density grids are derived by dividing the...

Dar Es Salaam Land Use and Informal Settlement Data Set

Sliuzas, R.V.; Hill, A.; Lindner, C.; Greiving, S.
The Dar es Salaam Land Use and Informal Settlement Data Set represents urban land use and consolidation of informal settlements for the years 1982, 1992, 1998, and 2002, in Dar es Salaam, Tanzania. The land use categories are informal settlement areas, planned residential areas, ocean and estuaries, vacant and agriculture lands, and other urban features such as industrial or recreation areas. The data are based on the World Geodetic System spheroid of 1984 and uses...

Gridded Population of the World, Version 3 (GPWv3): Population Density Grid

Center For International Earth Science Information Network-CIESIN-Columbia University; Centro Internacional De Agricultura Tropical-CIAT
Gridded Population of the World, Version 3 (GPWv3) consists of estimates of human population for the years 1990, 1995, and 2000 by 2.5 arc-minute grid cells and associated data sets dated circa 2000. A proportional allocation gridding algorithm, utilizing more than 300,000 national and sub-national administrative units, is used to assign population values to grid cells. The population density grids are derived by dividing the population count grids by the land area grid and represent...

Millennium Ecosystem Assessment: MA Biodiversity

Millennium Ecosystem Assessment
The Millennium Ecosystem Assessment: MA Biodiversity data set provides data and information on amphibians, disease agents (extent and distribution of infectious and parasitic diseases), drylands (cattle, pasture and shoats), Islands (fishing pressure, sewage pollution index and tourism), loss of natural land cover (biomes and realms), polar population, species distribution models, and terrestrial ecoregions and realms. Biodiversity is defined as the variability among living organisms from all sources, including terrestrial, marine, and other aquatic ecosystems and...

Last of the Wild Project, Version 2, 2005 (LWP-2): Global Human Influence Index (HII) Dataset (IGHP)

Wildlife Conservation Society-WCS; Center For International Earth Science Information Network-CIESIN-Columbia University
The Global Human Influence Index Dataset of the Last of the Wild Project, Version 2, 2005 (LWP-2) 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...

Ross Sea unconformities digital grids in depth and two-way time

Christopher Sorlien & Douglas S. Wilson
This data set includes digital 1 km grids of sub-bottom stratigraphy of most of Ross Sea. In addition to acoustic basement (same as top syn-rift sedimentary rocks in Central Trough and probably other basins), these grids include Oligocene and Miocene horizons that are unconformities in most areas. A sea floor grid is also included. Except for the sea floor grid, the grids are trimmed to be relatively close to control of interpreted seismic stratigraphy. The...

West Africa Coastal Vulnerability Mapping: Mangrove Forests Distribution, 2000 Polygon

Giri, C.; Ochieng, E.; Tieszen, L.L.; Zhu, Z.; Singh, A.; Loveland, T.; Masek, J.; Duke, N.
The West Africa Coastal Vulnerability Mapping: Mangrove Forests Distribution, 2000 Polygon data set was derived from the 30m resolution NASA Socioeconomic Data and Applications Center (SEDAC) Global Mangrove Forests Distribution, 2000 raster data set. It represents the distribution of mangrove forests within 200 kilometers of the coast. The global raster data set is a compilation of the extent of mangrove forests from the Global Land Survey and the Landsat archive with hybrid supervised and unsupervised...
