The National Geospatial Digital Archive

A Collaborative Initiative



From the first colonial maps to the satellite imagery of the 21st century, cartographic information has helped define and frame our view of the United States. Geospatial imagery is now a critical tool for state and federal researchers pursuing greater understandings of complex matters including: Disaster Relief, Census Data, and Land Use Management.

Concerned that millions of nationally important digital information resources are in danger of being lost or corrupted, the Library of Congress has formed The National Digital Information Infrastructure and Preservation Program (NDIIPP).

As partners in the project the university libraries of UCSB and Stanford are leading the formation of the National Geospatial Digital Archive (NGDA), a collecting network for the archiving of geospatial images and data.

  • The Objectives of the Project:
  • Create a new national federated network committed to archiving geospatial imagery and data.
  • Investigate the proper and optimal roles of such a federated archive.
  • Collect and archive major segments of at-risk digital geospatial data and images.
  • Develop best practices for the presentation of archived digital geospatial data.
  • Develop partner communication mechanisms for the project and then ongoing.
  • Develop a series of policy agreements governing retention, rights management, obligations of partners, interoperability of systems, and exchange of digital objects.
