The Analytical Geomagnetic Data Center of the Trans-Regional INTERMAGNET Segment is operated by the Geophysical Center of the Russian Academy of Sciences. It offers interactive access to magnetic observatory data from Russia and nearby states, plus spaceborne data products. The MAGNUS system provides automated real-time recognition of artificial disturbances and estimation of geomagnetic activity.
The Spatial Data Repository provides geographically linked health and demographic data from The DHS Program and the U.S. Census Bureau for mapping in a geographic information system. Data products include survey boundaries, indicator data, modeled map surfaces, geospatial covariates, population estimates, and a local data mapping tool.

CUGIR is a repository offering datasets and scanned maps. Datasets can be browsed by theme or found by zooming a map to an area and clicking a search button. Themes include boundaries, geology, agriculture, land cover, transportation, climate and elevation. The scanned maps section provides access to all map holdings.
The National Archive of Marine Seismic Surveys is a USGS data website presenting marine seismic reflection data within the United States. Visitors can click the map to select nearby surveys, mouse over survey names to highlight surveys, filter surveys by keyword and open individual survey pages for data and information.
The Cross-National Equivalent File is a household panel data package of equivalently defined variables for 9 general population household panel surveys. It harmonizes and makes available cross-national panel data for social science research, with country-specific data offered online through the CNEF-Investigator platform. Access requires an application.
The Environmental Data Initiative preserves and provides open access to environmental and ecological data, with information-rich metadata and a secure, persistent archive. It supports publishing and reusing data through tools, a REST API for workflow automation, and personalized data catalogs. Authentication for API access becomes required on July 30, 2026.
