All known Subclasses: org.geotools.referencing.operation.DefaultConcatenatedOperation, org.geotools.referencing.operation.DefaultSingleOperation,
| AbstractCoordinateOperation | | public class AbstractCoordinateOperation extends AbstractIdentifiedObject implements CoordinateOperation(Code) | | Establishes an association between a source and a target coordinate reference system,
and provides a
for transforming coordinates in
the source CRS to coordinates in the target CRS. Many but not all coordinate operations (from
A to
B)
also uniquely define the inverse operation (from
B to
A).
In some cases, the operation method algorithm for the inverse operation is the same
as for the forward algorithm, but the signs of some operation parameter values must
be reversed. In other cases, different algorithms are required for the forward and
inverse operations, but the same operation parameter values are used. If (some)
entirely different parameter values are needed, a different coordinate operation
shall be defined.
This class is conceptually abstract, even if it is technically possible to
instantiate it. Typical applications should create instances of the most specific subclass with
Default prefix instead. An exception to this rule may occurs when it is not possible to
identify the exact type.

| getAccuracy | | public double getAccuracy()(Code) | | Convenience method returning the accuracy in meters. The default implementation delegates

| getAccuracy | | public static double getAccuracy(CoordinateOperation operation)(Code) | | Convenience method returning the accuracy in meters for the specified operation. This method
try each of the following procedures and returns the first successful one:
- If a
positional accuracy is found with a
linear unit, then this accuracy estimate is converted to
and returned.
- Otherwise, if the operation is a
, then returns
0 since a conversion is by definition accurates up to rounding errors.
- Otherwise, if the operation is a
, then
checks if the datum shift were applied with the help of Bursa-Wolf parameters.
This procedure looks for Geotools-specific
PositionalAccuracyImpl.DATUM_SHIFT_APPLIED DATUM_SHIFT_APPLIED and
PositionalAccuracyImpl.DATUM_SHIFT_OMITTED DATUM_SHIFT_OMITTED metadata.
If a datum shift has been applied, returns 25 meters. If a datum shift should have
been applied but has been omitted, returns 1000 meters. The 1000 meters value is
higher than the highest value (999 meters) found in the EPSG database version 6.7.
The 25 meters value is the next highest value found in the EPSG database for a
significant number of transformations.
- Otherwise, if the operation is a
,
returns the sum of the accuracy of all components.
Parameters:
operation - The operation to inspect for accuracy. The accuracy estimate (always in meters), or NaN if unknow.
