Enum Constant Details

NORMALIZATION

public static final ContextualParameters.MatrixRole NORMALIZATION

Matrix for converting angular degrees to radians, or any other linear operations needed before to apply a non-linear operation. For example, in a map projection, this matrix is typically (but not necessarily) as below:

$$\left[\begin{array}{ccc}\pi /180& 0& -{\lambda }_0\cdot (\pi /180)\\ 0& \pi /180& 0\\ 0& 0& 1\end{array}\right]$$

INVERSE_NORMALIZATION

public static final ContextualParameters.MatrixRole INVERSE_NORMALIZATION

Inverse of the NORMALIZATION matrix. For example, in a map projection, this matrix is typically (but not necessarily) as below:

$$\left[\begin{array}{ccc}\mathrm{180}/\mathrm{\pi }& 0& {\lambda }_0\\ 0& \mathrm{180}/\mathrm{\pi }& 0\\ 0& 0& 1\end{array}\right]$$

DENORMALIZATION

public static final ContextualParameters.MatrixRole DENORMALIZATION

Matrix for scaling Cartesian coordinates to the size of the planet, or any other linear operations needed after execution of a non-linear operation. For example, in a map projection, this matrix is typically (but not necessarily) as below:

$$\left[\begin{array}{ccc}a\cdot k_0& 0& \mathrm{FE}\\ 0& a\cdot k_0& \mathrm{FN}\\ 0& 0& 1\end{array}\right]$$

INVERSE_DENORMALIZATION

public static final ContextualParameters.MatrixRole INVERSE_DENORMALIZATION

Inverse of the DENORMALIZATION matrix.

Method Details

values

public static ContextualParameters.MatrixRole[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static ContextualParameters.MatrixRole valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

Illegal­Argument­Exception - if this enum class has no constant with the specified name

Null­Pointer­Exception - if the argument is null
