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".

Since:

2.2

Field Detail

SRC_DIM

public static final org.opengis.parameter.ParameterDescriptor SRC_DIM

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

TGT_DIM

public static final org.opengis.parameter.ParameterDescriptor TGT_DIM

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

SRC_SEMI_MAJOR

public static final org.opengis.parameter.ParameterDescriptor SRC_SEMI_MAJOR

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

SRC_SEMI_MINOR

public static final org.opengis.parameter.ParameterDescriptor SRC_SEMI_MINOR

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

TGT_SEMI_MAJOR

public static final org.opengis.parameter.ParameterDescriptor TGT_SEMI_MAJOR

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

TGT_SEMI_MINOR

public static final org.opengis.parameter.ParameterDescriptor TGT_SEMI_MINOR

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

DX

public static final org.opengis.parameter.ParameterDescriptor 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 org.opengis.parameter.ParameterDescriptor 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 org.opengis.parameter.ParameterDescriptor DZ

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

Constructor Detail

GeocentricTranslation.Provider

public GeocentricTranslation.Provider()

Constructs a default provider.

Method Detail

getOperationType

protected java.lang.Class getOperationType()

Returns the operation type.

Overrides:

getOperationType in class MathTransformProvider

createMathTransform

protected org.opengis.referencing.operation.MathTransform createMathTransform(org.opengis.parameter.ParameterValueGroup values)
                                                                       throws org.opengis.parameter.ParameterNotFoundException

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

Specified by:

createMathTransform in class MathTransformProvider

Parameters:

fill

protected void fill(BursaWolfParameters parameters,
                    org.opengis.parameter.ParameterValueGroup values)
