@Immutable
public class DefaultEngineeringCRS
extends AbstractSingleCRS
implements EngineeringCRS

A contextually local coordinate reference system. It can be divided into two broad categories:

• earth-fixed systems applied to engineering activities on or near the surface of the earth;
• CRSs on moving platforms such as road vehicles, vessels, aircraft, or spacecraft.

Used with CS type(s)

Cartesian, Affine, Ellipsoidal, Spherical, Cylindrical, Polar, Vertical, Linear

Field Detail

CARTESIAN_2D

public static final DefaultEngineeringCRS CARTESIAN_2D

A two-dimensional Cartesian coordinate reference system with x, y axes in metres. By default, this CRS has no transformation path to any other CRS (i.e. a map using this CS can't be reprojected to a geographic coordinate reference system for example).

CARTESIAN_3D

public static final DefaultEngineeringCRS CARTESIAN_3D

A three-dimensional Cartesian coordinate reference system with x, y, z axes in metres. By default, this CRS has no transformation path to any other CRS (i.e. a map using this CS can't be reprojected to a geographic coordinate reference system for example).

GENERIC_2D

public static final DefaultEngineeringCRS GENERIC_2D

A two-dimensional wildcard coordinate system with x, y axes in metres. At the difference of CARTESIAN_2D, this coordinate system is treated specially by the default coordinate operation factory with loose transformation rules: if no transformation path were found (for example through a derived CRS), then the transformation from this CRS to any CRS with a compatible number of dimensions is assumed to be the identity transform. This CRS is useful as a kind of wildcard when no CRS were explicitly specified.

GENERIC_3D

public static final DefaultEngineeringCRS GENERIC_3D

A three-dimensional wildcard coordinate system with x, y, z axes in metres. At the difference of CARTESIAN_3D, this coordinate system is treated specially by the default coordinate operation factory with loose transformation rules: if no transformation path were found (for example through a derived CRS), then the transformation from this CRS to any CRS with a compatible number of dimensions is assumed to be the identity transform. This CRS is useful as a kind of wildcard when no CRS were explicitly specified.

Constructor Detail

DefaultEngineeringCRS

public DefaultEngineeringCRS(EngineeringCRS crs)

Constructs a new enginnering CRS with the same values than the specified one. This copy constructor provides a way to convert an arbitrary implementation into a Geotk 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:

crs - The CRS to copy.

Since:

2.2

DefaultEngineeringCRS

public DefaultEngineeringCRS(String name,
                             EngineeringDatum datum,
                             CoordinateSystem cs)

Constructs an engineering CRS from a name.

Parameters:

name - The name.

datum - The datum.

cs - The coordinate system.

DefaultEngineeringCRS

public DefaultEngineeringCRS(Map<String,?> properties,
                             EngineeringDatum datum,
                             CoordinateSystem cs)

Constructs an engineering 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 Detail

castOrCopy

public static DefaultEngineeringCRS castOrCopy(EngineeringCRS object)

Returns a Geotk CRS 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 Geotk implementation, then the given object is returned unchanged. Otherwise a new Geotk implementation is created and initialized to the attribute values of the given object.

Parameters:

object - The object to get as a Geotk implementation, or null if none.

Returns:

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

Since:

3.18

wrap

@Deprecated
public static DefaultEngineeringCRS wrap(EngineeringCRS object)

Deprecated. Renamed castOrCopy.

Parameters:

object - The object to get as a Geotk implementation, or null if none.

Returns:

The given object as a Geotk implementation.

getDatum

public EngineeringDatum getDatum()

Returns the datum.

Specified by:

getDatum in interface EngineeringCRS

Specified by:

getDatum in interface SingleCRS

Overrides:

getDatum in class AbstractSingleCRS

Returns:

The datum.

formatWKT

public String formatWKT(Formatter formatter)

Formats the inner part of a Well Known Text (WKT) element.

Specified by:

formatWKT in interface Formattable

Overrides:

formatWKT in class AbstractCRS

Parameters:

formatter - The formatter to use.

Returns:

The name of the WKT element type, which is "LOCAL_CS".
