Check Extent

This rule checks for a valid Bounding Extent (a spatial extent) and a Temporal Extent. This rule 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

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

End

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