     specification=ISO_19115)
default RepresentativeFraction getEquivalentScale()

Level of detail expressed as the scale of a comparable hardcopy map or chart.

Returns:

level of detail expressed as the scale of a comparable hardcopy, or null.

equivalentScale, vertical, angularDistance and levelOfDetail not provided.

Unit:

Distance

getVertical

@Profile(level=CORE)
@UML(identifier="vertical",
     obligation=CONDITIONAL,
     specification=ISO_19115)
default Double getVertical()

Vertical sampling distance.

Upcoming API change — units of measurement
The return type of this method may change in GeoAPI 4.0. It may be replaced by the Length type in order to provide unit of measurement together with the value.

     specification=ISO_19115)
default Double getAngularDistance()

Angular sampling measure.

Upcoming API change — units of measurement
The return type of this method may change in GeoAPI 4.0. It may be replaced by the Angle type in order to provide unit of measurement together with the value.

Returns:

the angular sampling measure, or null.
