Why was the data set created?

This ArcView GIS layer is the geologic interpretation of the Gulf of Mexico GLORIA data.

    Other_Citation_Details:
    The geologic interpretation of the GLORIA images found in the atlas, I-1864-A,B, weredigitized and ARC/INFO coverages created. Those coverages were combined to create a single, psuedo-color coded interpretive map/image for DDS-15. Unfortunately, the coverages were subsequently lost. Rather than re-digitize the mosaics, the decision was made to re-create the coverages based on the image from DDS-15.

    Source_Contribution:
    The image showing the geologic interpretation of the Gulf of Mexico GLORIA data was created by digitizing the expanded interpretations from I-1864-A,B. The coverages were combined to create a single psuedo-color coded interpretive map/image for DDS-15. Unfortunately, the ARC coverages were lost. Rather than re-digitize the interpretations, the decision was made to re-create the coverages based on the DDS-15 image.
  2. How were the data generated, processed, and modified?
    Date: 19-Oct-1998 (process 1 of 7)
    The geologic interpretation image was taken from the CD-ROM DDS-15 and registered to a 250 meter, georeferenced GLORIA image for the entire Gulf of Mexico. When the geologic interpretation image was registered, the image was then rasterized to create vector outlines. Person who carried out this activity:

    Edited the metadata to remove errors flagged by MP. Filled out the citation information including adding the edition, suggested citation, adding the DOI link and a link to the data page. Added USGS Thesaurus and ISO 19115 Topic Category theme keywords. Added the link to the browse graphic. Removed unrequired elements with a value of "unknown". Indicated in some required elements that information was unavailable from the original metadata. Added links to the source citations. Additional small edits to the metadata were made to be consistent with current standards. Updated the distribution liability to an approved FSP disclaimer statement. Updated the distribution format and provided links to the data removing a redundant digital transfer method. The metadata date was updated, but not the metadata contact. The metadata contact email was updated to a valid link with an explanation in the contact instructions (20230822).
