@UML(identifier="EX_VerticalExtent", specification=ISO_19115) public interface VerticalExtent
Vertical domain of dataset.
Method Summary | |
---|---|
Double |
getMaximumValue()
Returns the highest vertical extent contained in the dataset. |
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. |

Departure from OGC/ISO specification:
ISO 19115 specifies a genericCoordinateReferenceSystem
instead than the more restrictiveVerticalCRS
. GeoAPI uses the more specific type for type-safety and consistency withVerticalExtent
usage. However this restriction prevents usage of Height above the ellipsoid when only the constants defined in theVerticalDatumType
code list are used. If such height is wanted, implementors need to extend the above code list with their ownELLIPSOIDAL
constant.
