public class DefaultSphericalCS
extends AbstractCS
implements SphericalCS

A 2- or 3-dimensional coordinate system with one distance measured from the origin and two angular coordinates. In the two-dimensional case, the radius is omitted and may be implicitly an ellipsoid surface. Not to be confused with an ellipsoidal coordinate system based on an ellipsoid "degenerated" into a sphere.

Permitted associations

Used with CRS	Permitted axis names
Geocentric	“Spherical Latitude”, “ Spherical Longitude”, “Geocentric Radius”
Engineering	unspecified

Immutability and thread safety

This class is immutable and thus thread-safe if the property values (not necessarily the map itself) and the Coordinate­System­Axis instances given to the constructor are also immutable. Unless otherwise noted in the javadoc, this condition holds if all components were created using only SIS factories and static constants.

Since:

0.4

Constructor Details

DefaultSphericalCS

public DefaultSphericalCS(Map<String,?> properties,
 CoordinateSystemAxis axis0,
 CoordinateSystemAxis axis1,
 CoordinateSystemAxis axis2)

Constructs a three-dimensional coordinate system from a set of properties. The properties map is given unchanged to the super-class constructor. The following table is a reminder of main (not all) properties:

Recognized properties (non exhaustive list)

Property name	Value type	Returned by
"name"	ReferenceIdentifier or String	AbstractIdentifiedObject.getName()
"alias"	GenericName or Char­Sequence (optionally as array)	AbstractIdentifiedObject.getAlias()
"identifiers"	ReferenceIdentifier (optionally as array)	AbstractIdentifiedObject.getIdentifiers()
"remarks"	InternationalString or String	AbstractIdentifiedObject.getRemarks()

Parameters:

properties - the properties to be given to the identified object.

axis0 - the first axis (e.g. “Spherical latitude”).

axis1 - the second axis (e.g. “Spherical longitude”).

axis2 - the third axis (e.g. “Geocentric radius”).

• Geodetic­Object­Factory.create­Spherical­CS(Map, Coordinate­System­Axis, Coordinate­System­Axis, Coordinate­System­Axis)

DefaultSphericalCS

public DefaultSphericalCS(Map<String,?> properties,
 CoordinateSystemAxis axis0,
 CoordinateSystemAxis axis1)

Constructs a two-dimensional coordinate system from a set of properties. The given axes shall be angular measurements, without radius. The properties map is given unchanged to the super-class constructor.

Parameters:

properties - the properties to be given to the identified object.

axis0 - the first axis (e.g. “Spherical latitude”).

axis1 - the second axis (e.g. “Spherical longitude”).

Since:

1.4

DefaultSphericalCS

protected DefaultSphericalCS(SphericalCS cs)

Creates a new coordinate system with the same values than the specified one. This copy constructor provides a way to convert an arbitrary implementation into a SIS 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.

Parameters:

cs - the coordinate system to copy.

See Also:

• cast­Or­Copy(Spherical­CS)

Method Details

castOrCopy

public static DefaultSphericalCS castOrCopy(SphericalCS object)

Returns a SIS coordinate system implementation with the same values than the given arbitrary implementation. If the given object is null, then this method returns null. Otherwise if the given object is already a SIS implementation, then the given object is returned unchanged. Otherwise a new SIS implementation is created and initialized to the attribute values of the given object.

Parameters:

object - the object to get as a SIS implementation, or null if none.

Returns:

a SIS implementation containing the values of the given object (may be the given object itself), or null if the argument was null.

getInterface

public Class<? extends SphericalCS> getInterface()

Returns the GeoAPI interface implemented by this class. The SIS implementation returns Spherical­CS.class.

Note for implementers

Subclasses usually do not need to override this method since GeoAPI does not define Spherical­CS sub-interface. Overriding possibility is left mostly for implementers who wish to extend GeoAPI with their own set of interfaces.

Overrides:

get­Interface in class Abstract­CS

Returns:

Spherical­CS.class or a user-defined sub-interface.

forConvention

public DefaultSphericalCS forConvention(AxesConvention convention)

Returns a coordinate system equivalent to this one but with axes rearranged according the given convention. If this coordinate system is already compatible with the given convention, then this method returns this.

Overrides:

for­Convention in class Abstract­CS

Parameters:

convention - the axes convention for which a coordinate system is desired.

Returns:

a coordinate system compatible with the given convention (may be this).
