public class DefaultImageCRS
extends AbstractSingleCRS
implements ImageCRS

An engineering coordinate reference system applied to locations in images. Image coordinate reference systems are treated as a separate sub-type because a separate user community exists for images with its own terms of reference.

Used with CS type(s)
Cartesian, Affine

Constructor Details

DefaultImageCRS

public DefaultImageCRS(ImageCRS crs)

Constructs a new image 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

DefaultImageCRS

public DefaultImageCRS(String name,
 ImageDatum datum,
 AffineCS cs)

Constructs an image CRS from a name.

Parameters:

name - The name.

datum - The datum.

cs - The coordinate system.

DefaultImageCRS

public DefaultImageCRS(Map<String,?> properties,
 ImageDatum datum,
 AffineCS cs)

Constructs an image 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 Details

getCoordinateSystem

public AffineCS getCoordinateSystem()

Returns the coordinate system.

Specified by:

getCoordinateSystem in interface CoordinateReferenceSystem

Specified by:

getCoordinateSystem in interface ImageCRS

Specified by:

getCoordinateSystem in interface SingleCRS

Overrides:

getCoordinateSystem in class AbstractCRS

Returns:

The coordinate system.

getDatum

public ImageDatum getDatum()

Returns the datum.

Specified by:

getDatum in interface ImageCRS

Specified by:

getDatum in interface SingleCRS

calculateHashCode

public int calculateHashCode()

Returns a hash value for this geographic CRS.

Overrides:

calculateHashCode 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.
