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

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 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 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 non-GeoTools 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 non-GeoTools implementations. Use the constructor expecting a defining conversion for more determinist result.The properties are given unchanged to the super-class 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 super-class 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 super-class 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.
