AUXILIARY_SPHERE_TYPE

public static final ParameterDescriptor AUXILIARY_SPHERE_TYPE

The Auxiliary Sphere Type parameter accepts:

• 0 (use semimajor axis or radius of the geographic coordinate system)
• 1 (use semiminor axis or radius)
• 2 (calculate and use authalic radius), or 3 (use authalic radius and convert geodetic latitudes to authalic latitudes).

Geotools only supports 0 for the moment

FAKE_ESRI_STANDARD_PARALLELL

public static final ParameterDescriptor FAKE_ESRI_STANDARD_PARALLELL

Constructor Details

MercatorPseudoProvider

public MercatorPseudoProvider()

Constructs a new provider.

Method Details

getOperationType

public Class<CylindricalProjection> getOperationType()

Returns the operation type for this map projection.

Overrides:

getOperationType in class MapProjection.AbstractProvider

Returns:

The GeoAPI interface implemented by this operation.

createMathTransform

protected MathTransform createMathTransform(ParameterValueGroup parameters)
                                     throws ParameterNotFoundException

Creates a transform from the specified group of parameter values.

Specified by:

createMathTransform in class MathTransformProvider

Parameters:

parameters - The group of parameter values.

Returns:

The created math transform.

Throws:

ParameterNotFoundException - if a required parameter was not found.
