Check Extent

This FGDC conformance check determines if a valid Bounding Extent (a spatial extent) and Temporal Extent have been provided. The metadata file must contain both a spatial extent and a temporal extent in order to pass this conformance check.

This conformance check will also calculate the percent Bounding Extent coverage of the continental US.

Bounding Extent Best Practices

The following attributes must be populated to have a valid Spatial Extent:

West Coordinate

ISO 19115

//gmd:EX_GeographicBoundingBox/gmd:westBoundLongitude/gco:Decimal/text()

ISO 19115-3

//gex:EX_GeographicBoundingBox/gex:westBoundLongitude/gco:Decimal/text()

East Coordinate

ISO 19115

//gmd:EX_GeographicBoundingBox/gmd:eastBoundLongitude/gco:Decimal/text()

ISO 19115-3

//gex:EX_GeographicBoundingBox/gex:eastBoundLongitude/gco:Decimal/text()

North Coordinate

ISO 19115

//gmd:EX_GeographicBoundingBox/gmd:northBoundLatitude/gco:Decimal/text()

ISO 19115-3

//gex:EX_GeographicBoundingBox/gmd:northBoundLatitude/gco:Decimal/text()

South Coordinate

ISO 19115

//gmd:EX_GeographicBoundingBox/gmd:southBoundLatitude/gco:Decimal/text()

ISO 19115-3

//gex:EX_GeographicBoundingBox/gex:southBoundLatitude/gco:Decimal/text()

Temporal Extent Best Practices

Beginning

ISO 19115

//gmd:EX_TemporalExtent/gmd:extent/gml:TimePeriod/gml:beginPosition/text()

ISO 19115-3

//gex:EX_TemporalExtent/gex:extent/gml:TimePeriod/gml:beginPosition/text()

End

ISO 19115

//gmd:EX_TemporalExtent/gmd:extent/gml:TimePeriod/gml:endPosition/text()

ISO 19115-3

//gex:EX_TemporalExtent/gex:extent/gml:TimePeriod/gml:endPosition/text()
