Summary
The Global Rural-Urban Mapping Project (GRUMP) 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. The data products include population
count grids (raw counts), population density grids (per square ... km), land area
grids (actual area net of ice and water), mean geographic unit area grids,
urban extents grids, centroids, a national identifier grid, national
boundaries, coastlines, and settlement points. These products vary in
GIS-compatible data formats and geographic extents available (global, continent
[Antarctica not included], and country levels). A proportional allocation
gridding algorithm, utilizing more than 1,000,000 national and sub-national
geographic units, is used to assign population values to grid cells. Additional
global grids were created from the 30 arc-second grid at 1/4, 1/2, and 1 degree
resolutions. (Spatial reference metadata refers to global extent, 30 arc-second
resolution.) The 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 purpose is to allow
analysis of urban and rural population figures based on a consistent global
data set. The data are available from the Socioeconomic Data and Applications
Center (SEDAC) in American Standard Code for Information Interchange (ASCII),
ARC/INFO Grid, Band Interleaved by Line (BIL), Comma Separated Value (CSV),
Microsoft Excel (XLS), ESRI Shapefile (SHP), and Portable Document (PDF)
formats via direct download at http://sedac.ciesin.columbia.edu/gpw/.
