Global Rural-Urban Mapping Project, Version 1 (GRUMPv1): Land and Geographic Unit Area GridsEntry ID: CIESIN_SEDAC_GRUMPv1_LGUAG
Abstract: The Global Rural-Urban Mapping Project, Version 1 (GRUMPv1) consists of estimates of human population for the years 1990, 1995, and 2000 by 30 arc-second (1km) grid. The area grids measure land areas in square kilometers and the mean unit size (population-weighted) in square kilometers. The land area grid permits the summation of areas (net of permanent ice and water) at the same resolution as the ... population density, count, and urban-rural grids. The mean unit size grids provide a quantitative surface that indicates the size of the input unit(s) from which population count and density grids are derived. Additional global grids are created from the 30 arc-second grid at 1/4, 1/2, and 1 degree resolutions. This dataset is produced by the Columbia University Center for International Earth Science Information Network (CIESIN) in collaboration with the International Food Policy Research Institute (IFPRI), The World Bank, and Centro Internacional de Agricultura Tropical (CIAT).
The data in ARC/INFO Binary Grid (GRID), American Standard Code for Information Interchange (ASCII), Band Interleaved by Line (BIL) formats are available from the NASA Socioeconomic Data and Applications Center (SEDAC).
Purpose: To provide land area data for use with GRUMPv1 population and urban data as well as a quantitative measure of resolution of the input spatial units for GRUMPv1.
