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. 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 ... View entire text

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.
