  • 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:
      π/180 0 -λ0 (π/180) 0 π/180 0 0 0 1
    • 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:
      180/π 0 λ0 0 180/π 0 0 0 1
    • 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:
      a k0 0 FE 0 a k0 FN 0 0 1
    • 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 type, in the order they are declared.
      Returns:
      an array containing the constants of this enum type, in the order they are declared
    • valueOf

      public static ContextualParameters.MatrixRole valueOf(String name)
      Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (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 type has no constant with the specified name
      Null­Pointer­Exception - if the argument is null
