Field Detail

CARTESIAN_2D

public static final DefaultEngineeringCRS CARTESIAN_2D
A two-dimensional cartesian coordinate reference system with x, y axis 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 axis 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 axis 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 usefull 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 axis 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 usefull as a kind of wildcard when no CRS were explicitly specified.

Constructor Detail

DefaultEngineeringCRS

public DefaultEngineeringCRS(org.opengis.referencing.crs.EngineeringCRS crs)
Constructs a new enginnering 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.

Parameters:
crs - The CRS to copy.
Since:
2.2

DefaultEngineeringCRS

public DefaultEngineeringCRS(java.lang.String name,
                             org.opengis.referencing.datum.EngineeringDatum datum,
                             org.opengis.referencing.cs.CoordinateSystem cs)
Constructs an engineering CRS from a name.

Parameters:
name - The name.
datum - The datum.
cs - The coordinate system.

DefaultEngineeringCRS

public DefaultEngineeringCRS(java.util.Map<java.lang.String,?> properties,
                             org.opengis.referencing.datum.EngineeringDatum datum,
                             org.opengis.referencing.cs.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

getDatum

public org.opengis.referencing.datum.EngineeringDatum getDatum()
Returns the datum.

Specified by:
getDatum in interface org.opengis.referencing.crs.EngineeringCRS
Specified by:
getDatum in interface org.opengis.referencing.crs.SingleCRS
Overrides:
getDatum in class AbstractSingleCRS
Returns:
The datum.

hashCode

public int hashCode()
Returns a hash value for this derived 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 java.lang.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 "LOCAL_CS".
