Global Rural-Urban Mapping Project, Version 1 (GRUMPv1): National Identifier GridEntry ID: CIESIN_SEDAC_GRUMPv1_NATIDEN
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 cells and
associated datasets dated circa 2000. National Identifier Grid is derived from the land area grid to create a raster surface where pixels (cells) that cover the same nation or territory
have the same value. Note that the ... countries and territories are not official representations of country boundaries; rather, they represent the area covered by the statistical data as
provided. 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).
Purpose: To permit the summation of population values by country/territory and, in combination with other data layers, the summation of population values by irregular areas
represented in the other data layers and country/territory.
