public class DefaultVerticalCS

extends AbstractCS

implements org.opengis.referencing.cs.VerticalCS

A one-dimensional coordinate system used to record the heights (or depths) of points. Such a coordinate system is usually dependent on the Earth's gravity field, perhaps loosely as when atmospheric pressure is the basis for the vertical coordinate system axis. An exact definition is deliberately not provided as the complexities of the subject fall outside the scope of this specification. A shall have one axis.

Field Detail

ELLIPSOIDAL_HEIGHT

public static DefaultVerticalCS ELLIPSOIDAL_HEIGHT

A one-dimensional vertical CS with ellipsoidal height axis in metres.

GRAVITY_RELATED

public static DefaultVerticalCS GRAVITY_RELATED

A one-dimensional vertical CS with gravity-related height axis in metres.

DEPTH

public static DefaultVerticalCS DEPTH

A one-dimensional vertical CS with depth axis in metres.

Constructor Detail

DefaultVerticalCS

public DefaultVerticalCS(org.opengis.referencing.cs.VerticalCS cs)

Constructs a new coordinate system 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.

DefaultVerticalCS

public DefaultVerticalCS(java.lang.String name,
                         org.opengis.referencing.cs.CoordinateSystemAxis axis)

Constructs a coordinate system from a name.

Parameters:

name - The coordinate system name.

axis - The axis.

DefaultVerticalCS

public DefaultVerticalCS(java.util.Map properties,
                         org.opengis.referencing.cs.CoordinateSystemAxis axis)

Constructs a coordinate system from a set of properties. The properties map is given unchanged to the super-class constructor.

Parameters:

properties - Set of properties. Should contains at least "name".

axis - The axis.

Method Detail

isCompatibleDirection

protected boolean isCompatibleDirection(org.opengis.referencing.cs.AxisDirection direction)

Returns if the specified axis direction is allowed for this coordinate system. The default implementation accepts only vertical directions (i.e. UP and DOWN).

Overrides:

isCompatibleDirection in class AbstractCS

distance

public Measure distance(double[] coord1,
                        double[] coord2)
                 throws org.opengis.spatialschema.geometry.MismatchedDimensionException

Computes the distance between two points.

Overrides:

distance in class AbstractCS

Parameters:

coord1 - Coordinates of the first point.

coord2 - Coordinates of the second point.

Returns:

The distance between and .

Throws:

org.opengis.spatialschema.geometry.MismatchedDimensionException - if a coordinate doesn't have the expected dimension.
