The United States Geoscience Information Network (USGIN) initiative is the product of a partnership between the Association of American State Geologists (AASG) and the United States Geological Survey (USGS) created to facilitate discovery of, and access to, geoscience information provided by state and federal geological surveys of the United States. In other words, USGIN is a distributed data-sharing network that uses open-source software and existing World Wide Web infrastructure and browsers. Anyone can access the data shared over USGIN, and any data that is shared according to USGIN specifications is automatically a part of the network.
DGS has entered into a partnership with the Arizona Geological Survey (AZGS) to participate in USGIN by establishing a metadata clearinghouse node for Delaware geoscience information. Metadata on the Delaware node can be searched through other USGIN nodes, associated datasets can be downloaded, and any OGC (WMS,WFS,WCS) map services can be displayed through remote map-based interfaces. WFS map services on USGIN will be also configured to communicate through Geoscience Markup Language (GeoSciML.) DGS holds several data sources on the geology of Delaware that would fit into the mission of USGIN and it would be beneficial to both USGIN and DGS for these resources to be discoverable and accessible to a wider audience.
As a result of this project, DGS will operate the following:
- CSW-compliant metadata catalog node on the USGIN
- WMS, WFS, and WCS map services for several DGS geologic maps
- GeoSciML configured WFS services
- published OGC map services in OneGeology (http://www.onegeology.org/)
