If sampling EML is used within methods, does that obviate geographicCoverage? Or should those sites be repeated or referenced? EML Best Practices v.2, p. 22-23. "One geographicCoverage element should be included, whose boundingCoordinates describe the extent of the data....Additional geographicCoverage elements may be entered at the dataset level if there are significant distances between study sites and it would be confusing if they were grouped into one bounding box." 6 decimal places.
