public class DefaultVerticalCRS
- extends AbstractSingleCRS
- implements VerticalCRS
A 1D coordinate reference system used for recording heights or depths. Vertical CRSs make use
of the direction of gravity to define the concept of height or depth, but the relationship with
gravity may not be straightforward.
By implication, ellipsoidal heights (h) cannot be captured in a vertical coordinate
reference system. Ellipsoidal heights cannot exist independently, but only as inseparable part
of a 3D coordinate tuple defined in a geographic 3D coordinate reference system. However GeoAPI
does not enforce this rule. This class defines a ELLIPSOIDAL_HEIGHT
constant in
violation with ISO 19111; this is considered okay if this constant is used merely as a step
toward the construction of a 3D CRS (for example in a transient state during WKT parsing),
or for passing arguments in methods enforcing type-safety.

ELLIPSOIDAL_HEIGHT
public static final DefaultVerticalCRS ELLIPSOIDAL_HEIGHT
- Default vertical coordinate reference system using ellipsoidal datum.
Ellipsoidal heights are measured along the normal to the ellipsoid
used in the definition of horizontal datum.

GEOIDAL_HEIGHT
public static final DefaultVerticalCRS GEOIDAL_HEIGHT
- Default vertical coordinate reference system using geoidal datum.

DefaultVerticalCRS
public DefaultVerticalCRS(VerticalCRS crs)
- Constructs a new vertical CRS with the same values than the specified one.
This copy constructor provides a way to wrap an arbitrary implementation into a
Geotools one or a user-defined one (as a subclass), usually in order to leverage
some implementation-specific API. This constructor performs a shallow copy,
i.e. the properties are not cloned.
- Since:
- 2.2
DefaultVerticalCRS
public DefaultVerticalCRS(VerticalDatum datum,
VerticalCS cs)
- Constructs a vertical CRS with the same properties than the given datum.
The inherited properties include the name and aliases.
- Parameters:
datum
- The datum.cs
- The coordinate system.- Since:
- 2.5
DefaultVerticalCRS
public DefaultVerticalCRS(String name,
VerticalDatum datum,
VerticalCS cs)
- Constructs a vertical CRS from a name.
- Parameters:
name
- The name.datum
- The datum.cs
- The coordinate system.
DefaultVerticalCRS
public DefaultVerticalCRS(Map<String,?> properties,
VerticalDatum datum,
VerticalCS cs)
- Constructs a vertical CRS from a set of properties. The properties are given unchanged to
the super-class constructor.
- Parameters:
properties
- Set of properties. Should contains at least "name"
.datum
- The datum.cs
- The coordinate system.
getCoordinateSystem
public VerticalCS getCoordinateSystem()
- Returns the coordinate system.

getDatum
public VerticalDatum getDatum()
- Returns the datum.
- Specified by:
getDatum
in interface SingleCRS
- Specified by:
getDatum
in interface VerticalCRS

getDatum
in class AbstractSingleCRS
- Returns:
- The datum.
hashCode
public int hashCode()
- Returns a hash value for this geographic CRS.
- Overrides:
hashCode
in class AbstractSingleCRS
- Returns:
- The hash code value. This value doesn't need to be the same
in past or future versions of this class.
formatWKT
protected String formatWKT(Formatter formatter)
- Format the inner part of a
Well
Known Text (WKT) element.
- Overrides:
formatWKT
in class AbstractCRS
- Parameters:
formatter
- The formatter to use.
- Returns:
- The name of the WKT element type, which is
"VERT_CS"
