Interface  Description 

EllipsoidalTransform 
A
MathTransform where the source and/or the target coordinate system is ellipsoidal. 
LinearTransform 
A
MathTransform which can be represented by a matrix. 
Parameterized 
An object (usually a
MathTransform ) which can supply its parameters in a
ParameterValueGroup . 
Class  Description 

AbstractMathTransform 
Provides a default implementation for most methods required by the
MathTransform
interface. 
AbstractMathTransform1D 
Base class for math transforms that are known to be onedimensional in all cases.

AbstractMathTransform2D 
Base class for math transforms that are known to be twodimensional in all cases.

AbstractMathTransform2D.Parameters 
The parameters of the enclosing transform as a tuple of (normalize –
nonlinear kernel – denormalize) transforms.

AffineTransform2D 
Transforms twodimensional coordinate points using an affine transform.

ConcatenatedTransform 
Base class for concatenated transforms.

DimensionFilter 
A utility class for the separation of concatenation of
pass through transforms.

EarthGravitationalModel 
Transforms vertical coordinates using coefficients from the
Earth
Gravitational Model.

ExponentialTransform1D 
A one dimensional exponential transform.

GeocentricAffineTransform 
An affine transform applied on geocentric coordinates.

GeocentricTransform 
Transforms three dimensional geographic points to geocentric
coordinate points.

GridTransform 
Transforms a set of coordinate points using bilinear interpolation in a grid.

GridTransform2D 
A specialization of
GridTransform in the twodimensional case. 
LinearTransform1D 
A one dimensional, linear transform.

LogarithmicTransform1D 
A one dimensional, logarithmic transform.

MolodenskyTransform 
Two or threedimensional datum shift using the (potentially abridged) Molodensky transformation.

NadconTransform 
The NADCON transform (EPSG code 9613).

NTv2Transform 
Transform based on a NTv2 grid (EPSG code 9615).

PassThroughTransform 
Transform which passes through a subset of ordinates to another transform.

ProjectiveTransform 
A usually affine, or otherwise a projective transform.

VerticalTransform 
Base class for transformations from a height above the ellipsoid to a
height above the geoid.

WarpFactory 
Creates image
Warp objects for the given MathTransform2D . 
WarpTransform2D 
Wraps an arbitrary
Warp object as a twodimensional transform. 
Enum  Description 

GridType 
Whatever the grid values backing a
GridTransform are directly the target coordinates
or offsets to apply on the source coordinates. 
IterationStrategy 
Strategy for iterating over the point arrays given to
transform methods. 
MathTransforms
in the parent package.
Grid data
Some transforms are backed by a grid of data. This is the case for example of the
NADCON transform,
which implements a datum shift for the United States. The data may need to be downloaded
separately. To download the data, see the
geotksetup module.
