Navigation file opened in MS Excel, arc milliseconds for X and Y coordinates were converted to decimal degrees (by dividing each of the arc-millisecond values by 3,600,000 and creating the two new attribute fields X_DD and Y_DD) [excel file ##to##sda.xls]. A header line was added to the table in Excel.

Process_Description:
Edits to the metadata were made to fix any errors that MP v 2.9.36 flagged. This is necessary to enable the metadata to be successfully harvested for various data catalogs. In some cases, this meant adding text "Information unavailable" or "Information unavailable from original metadata" for those required fields that were left blank. Other minor edits were probably performed (title, publisher, publication place, etc.). The link to the data in the Identification_Information section had to be fixed. The link to the data in the Distribution_Information section had to be fixed. Attempted to modify http to https where appropriate. The link to the larger work citation had to be fixed. The metadata date (but not the metadata creator) was edited to reflect the date of these changes. The metadata available from a harvester may supersede metadata bundled within a download file. Compare the metadata dates to determine which metadata file is most recent.
