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 Detail

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 Detail

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
Overrides:
getDatum in class AbstractSingleCRS
Returns:
The datum.

hashCode

public int hashCode()
Returns a hash value for this geographic 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.
