public class DefaultProjectedCRS extends AbstractDerivedCRS implements ProjectedCRS
A 2D coordinate reference system used to approximate the shape of the earth on a planar surface. It is done in such a way that the distortion that is inherent to the approximation is carefully controlled and known. Distortion correction is commonly applied to calculated bearings and distances to produce values that are a close match to actual field values.Used with CS type(s) Cartesian

Constructor Detail

DefaultProjectedCRS
public DefaultProjectedCRS(ProjectedCRS crs)
Constructs a new projected 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 userdefined one (as a subclass), usually in order to leverage some implementationspecific API. This constructor performs a shallow copy, i.e. the properties are not cloned. Parameters:
crs
 The coordinate reference system to copy. Since:
 2.2

DefaultProjectedCRS
public DefaultProjectedCRS(String name, GeographicCRS base, MathTransform baseToDerived, CartesianCS derivedCS) throws MismatchedDimensionException
Constructs a projected CRS from a name. A default operation method is inferred from the math transform. This is a convenience constructor that is not garanteed to work reliably for nonGeoTools implementations. Use the constructor expecting a defining conversion for more determinist result. Parameters:
name
 The name.base
 Coordinate reference system to base the derived CRS on.baseToDerived
 The transform from the base CRS to returned CRS.derivedCS
 The coordinate system for the derived CRS. The number of axes must match the target dimension of the transformbaseToDerived
. Throws:
MismatchedDimensionException
 if the source and target dimension ofbaseToDeviced
don't match the dimension ofbase
andderivedCS
respectively. Since:
 2.5

DefaultProjectedCRS
public DefaultProjectedCRS(Map<String,Object> properties, GeographicCRS base, MathTransform baseToDerived, CartesianCS derivedCS) throws MismatchedDimensionException
Constructs a projected CRS from a set of properties. A default operation method is inferred from the math transform. This is a convenience constructor that is not garanteed to work reliably for nonGeoTools implementations. Use the constructor expecting a defining conversion for more determinist result.The properties are given unchanged to the superclass constructor.
 Parameters:
properties
 Name and other properties to give to the new derived CRS object and to the underlying projection.base
 Coordinate reference system to base the derived CRS on.baseToDerived
 The transform from the base CRS to returned CRS.derivedCS
 The coordinate system for the derived CRS. The number of axes must match the target dimension of the transformbaseToDerived
. Throws:
MismatchedDimensionException
 if the source and target dimension ofbaseToDeviced
don't match the dimension ofbase
andderivedCS
respectively. Since:
 2.5

DefaultProjectedCRS
public DefaultProjectedCRS(Map<String,Object> properties, OperationMethod method, GeographicCRS base, MathTransform baseToDerived, CartesianCS derivedCS) throws MismatchedDimensionException
Constructs a projected CRS from a set of properties. The properties are given unchanged to the superclass constructor. Parameters:
properties
 Name and other properties to give to the new derived CRS object and to the underlying projection.method
 A description of the method for the conversion.base
 Coordinate reference system to base the derived CRS on.baseToDerived
 The transform from the base CRS to returned CRS.derivedCS
 The coordinate system for the derived CRS. The number of axes must match the target dimension of the transformbaseToDerived
. Throws:
MismatchedDimensionException
 if the source and target dimension ofbaseToDeviced
don't match the dimension ofbase
andderivedCS
respectively.

DefaultProjectedCRS
public DefaultProjectedCRS(Map<String,?> properties, Conversion conversionFromBase, GeographicCRS base, MathTransform baseToDerived, CartesianCS derivedCS) throws MismatchedDimensionException
Constructs a projected CRS from a defining conversion. The properties are given unchanged to the superclass constructor. Parameters:
properties
 Name and other properties to give to the new projected CRS object.conversionFromBase
 The defining conversion.base
 Coordinate reference system to base the projected CRS on.baseToDerived
 The transform from the base CRS to returned CRS.derivedCS
 The coordinate system for the projected CRS. The number of axes must match the target dimension of the transformbaseToDerived
. Throws:
MismatchedDimensionException
 if the source and target dimension ofbaseToDerived
don't match the dimension ofbase
andderivedCS
respectively.
