Each link in the Navigation panel on the left side of this website corresponds with a specific USGIN support website.

• The Document Repository: The USGIN Document Repository acts as an upload point for USGIN data resources that cannot be hosted as USGIN web services.
• The Laboratory: The USGIN Laboratory acts as an informal USGIN workshop where data providers and data developers can discuss their experiences and request assistance.
• The Metadata Catalog: The USGIN Metadata Catalog allows users to find USGIN data resources by browsing the associated metadata records that describe them.
• The Metadata Wizard: The USGIN Metadata Wizard allows data providers to enter metadata records in the USGIN Metadata Catalog.

USGIN support websites are not part of the distributed network proper, where the vast majority of USGIN data is found, but they play a vital role in allowing users to access and discover data on the distributed network.

For a more detailed explanation about how these websites fit into the overarching structure of USGIN, see the About USGIN tutorial.
