Gridded Population of the World, Version 3 (GPWv3): National Identifier Grid
Entry ID:
CIESIN_SEDAC_GPWv3_NATIDEN
Summary
Abstract:
Gridded Population of the World, Version 3 (GPWv3) National Identifier Grid is derived from the land area grid to create a raster surface where pixels (cells) that cover the same country or territory have the same value. Note that the countries and territories are not official representations of countries boundaries; rather, they represent the area covered by the statistical data as provided. GPWv3 is produced by the Columbia University Center for International Earth Science Information Network (CIESIN) in collaboration with Centro Internacional de Agricultura Tropical (CIAT).
The data in ARC/INFO Grid, American Standard Code for Information Interchange (ASCII) and Band Interleaved by Line (BIL) formats are available from the NASA Socioeconomic Data and Applications Center (SEDAC). Purpose: To provide a raster representation of nation-states in GPWv3 for use in aggregating population data.

Access Constraints
From the start of instrument operations through January 1, 1998, all SeaWiFS
data is free and available to the public. Following January 1, 1998, SeaWiFS data for scientific research will ONLY be available to Authorized Users who have registered with the SeaWiFS Project. Any individual scientist who will be conducting research that employs SeaWiFS data must be a registered Authorized User. A single Authorized User cannot obtain data to be used anonymously by members of a research group; all of the members of the group must be Authorized Users.
Use Constraints
Publications of research results utilizing these data must acknowledge the
SeaWiFS Project and the Ocean Biology Processing Group (OBPG) at the NASA Goddard Space Flight Center, Greenbelt, MD, USA. Data Set Progress
