public final class AbridgedMolodensky extends GeocentricAffineBetweenGeographic
The provider for "Abridged Molodensky transformation" (EPSG:9605). This provider constructs transforms between two geographic reference systems without passing though a geocentric one. This class nevertheless extends GeocentricAffineBetweenGeographic because it is an approximation of GeocentricTranslation3D.

The translation terms (dx, dy and dz) are common to all authorities. But remaining parameters are specified in different ways depending on the authority:

  • EPSG defines "Semi-major axis length difference" and "Flattening difference" parameters.
  • OGC rather defines "src_semi_major", "src_semi_minor", "tgt_semi_major", "tgt_semi_minor" and "dim" parameters.

    • createMathTransform

      public org.opengis.referencing.operation.MathTransform createMathTransform(org.opengis.referencing.operation.MathTransformFactory factory, org.opengis.parameter.ParameterValueGroup values) throws org.opengis.util.FactoryException
      Creates an Abridged Molodensky transform from the specified group of parameter values.
      Specified by:
      createMathTransform in interface MathTransformProvider
      Overrides:
      createMathTransform in class GeocentricAffineBetweenGeographic
      Parameters:
      factory - the factory to use for creating concatenated transforms.
      values - the group of parameter values.
      Returns:
      the created Abridged Molodensky transform.
      Throws:
      org.opengis.util.FactoryException - if a transform cannot be created.

    • redimension

      @Deprecated public final org.opengis.referencing.operation.OperationMethod redimension(int sourceDimensions, int targetDimensions)
      Deprecated.
      ISO 19111:2019 removed source/target dimensions attributes.
      Returns the elements of the given array at an index computed from the given dimensions.
      Overrides:
      redimension in class DefaultOperationMethod
      Parameters:
      sourceDimensions - the desired number of input dimensions.
      targetDimensions - the desired number of output dimensions.
      Returns:
      the redimensioned operation method, or null if none.

    • inverse

      public AbstractProvider inverse()
      The inverse of GeodeticOperation is usually the same operation with parameter signs inverted.
      Overrides:
      inverse in class AbstractProvider
      Returns:
      this for most GeodeticOperation instances.
