National Geospatial Data Asset (NGDA) Portfolio Datasets

An NGDA is defined as a geospatial dataset that has been designated by the FGDC Steering Committee and meets at least one of the following criteria:

  • Used by multiple agencies or with agency partners such as State, Tribal and local governments;
  • Applied to achieve Presidential priorities as expressed by OMB;
  • Required to meet shared mission goals of multiple Federal agencies; or
  • Expressly required by statutory mandate

Together, these datasets comprise the NGDA Portfolio. The table below contains the official list of NGDA with a link to the metadata on Data.gov and GeoPlatform.gov, a link to their associated Theme, and the lead agency responsible for the NGDA. Below this table is a table of Retired or Changed NGDA.

For questions about NGDA, please contact the NGDATeam@fgdc.gov.

Note: The Data.gov and GeoPlatform.gov links on this page are manually validated twice a year.  Additionally, this list is updated with new information as it is received. It is understood that a manual process for ensuring an up-to-date reference list for the NGDA datasets is not optimal. Stay tuned while we work to identify processes based on automated ingestion of metadata from data.gov into the GeoPlatform.gov system.

Current Status: The NGDA team completed a manual audit of these links on February 10, 2021.  We are in the process of working with agencies, data.gov and GeoPlatform.gov to identify updated source locations and correct issues.

*Framework Theme: The framework themes of NGDA data are those that are produced and used by most organizations. Various surveys indicate that they are required by a majority of users, form a critical foundation for the National Spatial Data Infrastructure (NSDI), and have widespread usefulness. A cooperative approach to producing and sharing these common data benefits most organizations that use geographic data.
