- - ### Method Detail

    - #### UseExceptions

          public static void UseExceptions()

      Use exceptions instead of error return codes.

      This is the default behaviour : methods that in C/C++ return an OGRErr return code would throw a RuntimeException() in case the code it is different from ogr.OGRERR_NONE. By calling this method, you can get back to that original state if DontUseExceptions() was called in-between. This will only apply to the org.gdal.osr.* package.

      Since:
        Java bindings 1.7.0

    - #### DontUseExceptions

          public static void DontUseExceptions()

      Use return code instead of exceptions.

      By default, methods that in C/C++ return an OGRErr return code would throw a RuntimeException() in case the code is different from ogr.OGRERR_NONE. By calling this method, you can prevent the exception to be thrown and get the original error code (ogr.OGRERR_* codes) This will only apply to the org.gdal.osr.* package.

      Since:
        Java bindings 1.7.0

    - #### GetWellKnownGeogCSAsWKT

          public static String GetWellKnownGeogCSAsWKT(String definition)

      Utility function that returns the WKT definition of the SRS expressed as a well known Geog CS.

      Such a user input is what can be passed in to SpatialReference.SetWellKnownGeogCS().

      Parameters:
        `definition` - text definition to try to deduce SRS from.
      Returns:
        WKT definition

    - #### GetUserInputAsWKT

          public static String GetUserInputAsWKT(String definition)

      Utility function that returns the WKT definition of the SRS expressed as a user input.

      Such a user input is what can be passed in to SpatialReference.SetFromUserInput().

      Parameters:
        `definition` - text definition to try to deduce SRS from.
      Returns:
        WKT definition

    - #### GetWellKnownGeogCSAsWKT

          public static int GetWellKnownGeogCSAsWKT(String name,
                                                    String[] argout)

    - #### GetUserInputAsWKT

          public static int GetUserInputAsWKT(String name,
                                              String[] argout)

    - #### GetProjectionMethods

          public static Vector GetProjectionMethods()

    - #### GetProjectionMethodParameterList

          public static String[] GetProjectionMethodParameterList(String method,
                                                                  String[] username)

    - #### GetProjectionMethodParamInfo

          public static void GetProjectionMethodParamInfo(String method,
                                                          String param,
                                                          String[] usrname,
                                                          String[] type,
                                                          double[] defaultval)

    - #### CreateCoordinateTransformation

          public static CoordinateTransformation CreateCoordinateTransformation(SpatialReference src,
                                                                                SpatialReference dst)

      Create transformation object.
      Parameters:
        `src` - source spatial reference system.
        `dst` - target spatial reference system.
      Returns:
        a new CoordinateTransformation object, or null in case of failure
