The Center for Integrated Earth System Information (CIESIN) is a center within the Columbia Climate School at Columbia University. CIESIN conducts cutting-edge geospatially enabled research and develops interdisciplinary data and systems to advance understanding of human-environment interactions and support public policy and private decision making.
Notice: The contract for the CIESIN-managed NASA Socioeconomic Data and Applications Center (SEDAC) was terminated on 30 April 2025, and its data are no longer included in the NASA Earthdata or Data.gov catalogs. CIESIN prepared a spreadsheet with links to the data sets, available here.
