Double	getMinimumValue() Returns the lowest vertical extent contained in the dataset.
VerticalCRS	getVerticalCRS() Provides information about the vertical coordinate reference system to which the maximum and minimum elevation values are measured.

Method Detail

getMinimumValue

@UML(identifier="minimumValue",
     obligation=MANDATORY,
     specification=ISO_19115)
Double getMinimumValue()

Returns the lowest vertical extent contained in the dataset.

Returns:

Double mandatory for valid content, may be null for an invalid document.

getMaximumValue

@UML(identifier="maximumValue",
     obligation=MANDATORY,
     specification=ISO_19115)
Double getMaximumValue()

Returns the highest vertical extent contained in the dataset.

Returns:

Double mandatory for valid content, may be null for an invalid document.

getVerticalCRS

@UML(identifier="verticalCRS",
     obligation=MANDATORY,
     specification=ISO_19115)
VerticalCRS getVerticalCRS()

Provides information about the vertical coordinate reference system to which the maximum and minimum elevation values are measured. The CRS identification includes unit of measure.

Returns:

The vertical CRS.
