Global Rural-Urban Mapping Project, Version 1 (GRUMPv1): Population Count Grid
Entry ID:
CIESIN_SEDAC_GRUMPv1_POPCOUNT
Summary
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. A proportional allocation gridding algorithm, utilizing more than 1,000,000 national and sub-national geographic units, is used to assign population values (counts, in persons) to grid ...
![]() Purpose: To provide a time series of raster population data for ntegration with other data sets.

Quality
Channel data are accurate to within approximately +/- 0.2 percent based on sensor noise level of 0.4 data number (DN). Temperatures are accurate to within approximately 2 degrees Kelvin. Relative albedos in adjacent grid cells are accurate to within approximately 5 percent. However, absolute albedo values are approximate. Accuracies for the products are difficult to determine, given the limited ...
