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.

Field Details

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.

See Also:

• DefaultVerticalDatum.ELLIPSOIDAL
• DefaultVerticalCS.ELLIPSOIDAL_HEIGHT

GEOIDAL_HEIGHT

public static final DefaultVerticalCRS GEOIDAL_HEIGHT

Default vertical coordinate reference system using geoidal datum.

Since:

2.5

• DefaultVerticalDatum.GEOIDAL
• DefaultVerticalCS.GRAVITY_RELATED_HEIGHT

Constructor Details

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.

Method Details

getCoordinateSystem

public VerticalCS getCoordinateSystem()

calculateHashCode

public int calculateHashCode()

Returns a hash value for this geographic CRS.
