- To provide populated place (point) data with consistent population estimates.
- The primary output of the Global Rural Urban Mapping Project, Version 1 (GRUMPv1) are a series of grids representing estimated population counts and density for the years 1990, 1995, and 2000 at 30 arc-second (~1km) spatial resolution. GRUMPv1 represents a spatial reallocation of the Gridded Population of the World, Version 3 (GPWv3) population distribution in a way that moved populations from rural to urban portions of administrative units. More than 1,000,000 national and sub-national geographic units were used to assign population values (counts, in persons) to grid cells. Settlement Points, Revision 01 (v1.01) is an updated version of the Settlement Points, Version 1 (v1) used in the original population reallocation. Revision 01 includes improved geospatial location for selected settlements, as well as new georeferenced settlements. Version 1 was 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). Revision 01 was produced by the Columbia University Center for International Earth Science Information Network (CIESIN) in collaboration with the CUNY Institute for Demographic Research (CIDR).
