Enclosing class:

GeocentricTranslation

public static class GeocentricTranslation.Provider
extends MathTransformProvider

Base class for geocentric affine transform providers. This base class is the provider for the "Geocentric translations" operation (EPSG code 9603). The translation terms are the same for the 2 derived operations, "Position Vector 7-param. transformation" and "Coordinate Frame rotation".

Field Details

SRC_DIM

public static final ParameterDescriptor<Integer> SRC_DIM

The number of source geographic dimension (2 or 3). This is a Geotools-specific argument. If presents, an "Ellipsoid_To_Geocentric" transform will be concatenated before the geocentric translation.

TGT_DIM

public static final ParameterDescriptor<Integer> TGT_DIM

The number of target geographic dimension (2 or 3). This is a Geotools-specific argument. If presents, a "Geocentric_To_Ellipsoid" transform will be concatenated after the geocentric translation.

SRC_SEMI_MAJOR

public static final ParameterDescriptor<Double> SRC_SEMI_MAJOR

The operation parameter descriptor for the "src_semi_major" optional parameter value. This is a Geotools-specific argument. If presents, an "Ellipsoid_To_Geocentric" transform will be concatenated before the geocentric translation. Valid values range from 0 to infinity.

SRC_SEMI_MINOR

public static final ParameterDescriptor<Double> SRC_SEMI_MINOR

The operation parameter descriptor for the "src_semi_minor" optional parameter value. This is a Geotools-specific argument. If presents, an "Ellipsoid_To_Geocentric" transform will be concatenated before the geocentric translation. Valid values range from 0 to infinity.

TGT_SEMI_MAJOR

public static final ParameterDescriptor<Double> TGT_SEMI_MAJOR

The operation parameter descriptor for the "tgt_semi_major" optional parameter value. This is a Geotools-specific argument. If presents, a "Geocentric_To_Ellipsoid" transform will be concatenated after the geocentric translation. Valid values range from 0 to infinity.

TGT_SEMI_MINOR

public static final ParameterDescriptor<Double> TGT_SEMI_MINOR

The operation parameter descriptor for the "tgt_semi_minor" optional parameter value. This is a Geotools-specific argument. If presents, a "Geocentric_To_Ellipsoid" transform will be concatenated after the geocentric translation. Valid values range from 0 to infinity.

DX

public static final ParameterDescriptor<Double> DX

The operation parameter descriptor for the X-axis translation ("dx") parameter value. Valid values range from -infinity to infinity. Units are meters.

DY

public static final ParameterDescriptor<Double> DY

The operation parameter descriptor for the Y-axis translation ("dy") parameter value. Valid values range from -infinity to infinity. Units are meters.

DZ

public static final ParameterDescriptor<Double> DZ

The operation parameter descriptor for the Z-axis translation ("dz") parameter value. Valid values range from -infinity to infinity. Units are meters.

Constructor Details

Provider

public Provider()

Method Details

getOperationType

public Class<Transformation> getOperationType()

Returns the operation type.

Overrides:

getOperationType in class MathTransformProvider

Returns:

The GeoAPI interface implemented by this operation.

createMathTransform

protected MathTransform createMathTransform(ParameterValueGroup values)
                                     throws ParameterNotFoundException

Creates a math transform from the specified group of parameter values.

Specified by:

createMathTransform in class MathTransformProvider

Parameters:

values - The group of parameter values.

Returns:

The created math transform.

Throws:

ParameterNotFoundException - if a required parameter was not found.

fill

protected void fill(BursaWolfParameters parameters,
 ParameterValueGroup values)

Fill the specified Bursa-Wolf parameters according the specified values. This method is invoked automatically by createMathTransform(org.geotools.api.parameter.ParameterValueGroup).

Parameters:

parameters - The Bursa-Wold parameters to set.

values - The parameter values to read. Those parameters will not be modified.
