System Access - External

This area consists of several websites and systems outside the NCDC that maintains metadata.

  • GCMD

    NASA's Global Change Master Directory enables users to locate and obtain access to Earth Science data sets and services relevent to global climate change and Earth Science research.

  • NMMR

    NOAA's Metadata Managers Repository (NMMR) is the web based interface that hosts NOAA's metadata. This metadata is in the Federal Geographic Data Committee (FGDC) format.

  • Geodata

    The portal, also known as the Geospatial One-Stop, serves as a public gateway for improving access to geospatial information and data under the Geospatial One-Stop e-government initiative.


    The Global Observing Systems Information Center was established at the College of Marine Studies of the University of Delaware, to provide a single entry point for users for data and information produced by the global observing systems GCOS, GOOS, and GTOS.

  • MERMaid

    MERMAid allows users to organize their metadata records in various arrangements (i.e. by program, project, data type, personnel). Some of the key features in MERMAid include (1) user-defined roles and permissions at the metadata management and database levels; (2) change tracking; and (3) enhanced validation. Also, existing FGDC compliant metadata (in XML format) can be contributed and managed through MERMAid.
