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:
MI_GCP
└─geographicCoordinates……
Geographic or map position of the control point, in either two or three dimensions.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.

- 0.3

DefaultGCP
public DefaultGCP(org.opengis.metadata.spatial.GCP 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, ornull
if none.- See Also:
-
-
Method Details
-
castOrCopy
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 returnsnull
. - Otherwise if the given object is already an instance of
DefaultGCP
, then it is returned unchanged. - Otherwise a new
DefaultGCP
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, ornull
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.
- If the given object is

getGeographicCoordinates
public org.opengis.geometry.DirectPosition getGeographicCoordinates()Returns the geographic or map position of the control point, in either two or three dimensions.- Specified by:
getGeographicCoordinates
in interfaceorg.opengis.metadata.spatial.GCP
- Returns:
- geographic or map position of the control point, or
null
.
-
setGeographicCoordinates
public void setGeographicCoordinates(org.opengis.geometry.DirectPosition newValue) Sets the geographic or map position of the control point, in either two or three dimensions.- Parameters:
newValue
- the new geographic coordinates values.
-
getAccuracyReports
Returns the accuracy of a ground control point.- Specified by:
getAccuracyReports
in interfaceorg.opengis.metadata.spatial.GCP
- Returns:
- accuracy of a ground control point.
-
setAccuracyReports
public void setAccuracyReports(Collection<? extends org.opengis.metadata.quality.Element> newValues) Sets the accuracy of a ground control point.- Parameters:
newValues
- the new accuracy report values.
