Information on ground control point. Ground control points (GCP) are large marked targets on the ground, not to be confused with localization grid points embedded in some file formats like GeoTIFF or netCDF. The following property is mandatory in a well-formed metadata according ISO 19115:
└─geographicCoordinates……Geographic or map position of the control point, in either two or three dimensions.
- 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

DefaultGCPpublic DefaultGCP()Constructs an initially empty ground control point.
(GCP object)Constructs a new instance initialized with the values from the specified metadata object. This is a shallow copy constructor, since the other metadata contained in the given object are not recursively copied.

castOrCopyReturns 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
- Otherwise if the given object is already an instance of
DefaultGCP, then it is returned unchanged.
- Otherwise a new
DefaultGCPinstance is created using the copy constructor and returned. Note that this is a shallow copy operation, since the other metadata contained in the given object are not recursively copied.
