All Implemented Interfaces:
  `Serializable`, `Emptiable`, `LenientComparable`, `IdentifiedObject`, `Georectified`, `GridSpatialRepresentation`, `SpatialRepresentation`

public class DefaultGeorectified extends DefaultGridSpatialRepresentation implements Georectified
Grid whose cells are regularly spaced in a geographic or projected coordinate reference system. Any cell in the grid can be geolocated given its grid coordinate and the grid origin, cell spacing, and orientation indication of whether or not geographic.

The following properties are mandatory or conditional (i.e. mandatory under some circumstances) in a well-formed metadata according ISO 19115:

`MD_Georectified` `├─numberOfDimensions…………………………………………………` Number of independent spatial-temporal axes. `├─axisDimensionProperties……………………………………` Information about spatial-temporal axis properties. `│ ├─dimensionName……………………………………………………` Name of the axis. `│ └─dimensionSize……………………………………………………` Number of elements along the axis. `├─cellGeometry…………………………………………………………………` Identification of grid data as point or cell. `├─transformationParameterAvailability……` Whether parameters for transformation exists. `├─checkPointAvailability………………………………………` Whether geographic position points are available to test the accuracy of the georeferenced grid data. `├─checkPointDescription…………………………………………` Description of geographic position points used to test the accuracy of the georeferenced grid data. `├─cornerPoints…………………………………………………………………` Earth location in the coordinate reference system and the grid coordinate of the cells at opposite ends. `└─pointInPixel…………………………………………………………………` Point in a pixel corresponding to the Earth location of the pixel.
Providing the check point description implies that check point availability is `true`. The setter methods will ensure that this condition is not violated.

## Limitations

- Instances of this class are not synchronized for multi-threading. Synchronization, if needed, is caller's responsibility.
- Serialized objects of this class are not guaranteed to be compatible with future Apache SIS releases. Serialization support is appropriate for short term storage or RMI between applications running the same version of Apache SIS. For long term storage, use `XML` instead.

- ## Constructor Details

  - ### DefaultGeorectified

    public DefaultGeorectified()
    Constructs an initially empty georectified object.

  - ### DefaultGeorectified

    public DefaultGeorectified(Georectified object)
    Constructs a new instance initialized with the values from the specified metadata object. This is a shallow copy constructor, because the other metadata contained in the given object are not recursively copied.
    Parameters:
      `object` - the metadata to copy values from, or `null` if none.
    See Also:
      - `castOrCopy(Georectified)`

- ## Method Details

  - ### castOrCopy

    public static DefaultGeorectified castOrCopy(Georectified object)
    Returns a SIS metadata implementation with the values of the given arbitrary implementation. This method performs the first applicable action in the following choices:
    - If the given object is `null`, then this method returns `null`.
    - Otherwise if the given object is already an instance of `DefaultGeorectified`, then it is returned unchanged.
    - Otherwise a new `DefaultGeorectified` instance is created using the copy constructor and returned. Note that this is a shallow copy operation, because the other metadata contained in the given object are not recursively copied.
    Parameters:
      `object` - the object to get as a SIS implementation, or `null` if none.
    Returns:
      a SIS implementation containing the values of the given object (may be the given object itself), or `null` if the argument was null.

  - ### isCheckPointAvailable

    public boolean isCheckPointAvailable()
    Returns an indication of whether or not geographic position points are available to test the accuracy of the georeferenced grid data.
    Specified by:
      `isCheckPointAvailable` in interface `Georectified`
    Returns:

    Returns:
      description of geographic position points used to test accuracy, or `null`.

  - ### setCheckPointDescription

    public void setCheckPointDescription(InternationalString newValue)
    Sets the description of geographic position points used to test the accuracy of the georeferenced grid data.

    #### Effect on other properties

    If and only if the given `newValue` is non-null, then this method automatically sets the check point availability property to `true`.
    Parameters:
      `newValue` - the new check point description.
