- ## Constructor Details

  - ### CoordinateTransformation

    public CoordinateTransformation(SpatialReference src, SpatialReference dst)
    Deprecated.
    Create transformation object.

    Caution: the coordinate transformation object returned can be in a non working state if no coordinate transformation can be established between src and dst, and calling other methods on it can result in the process termination. It is recommended to use the CreateCoordinateTransformation(org.gdal.osr.SpatialReference, org.gdal.osr.SpatialReference) method instead.

    Parameters:
      `src` - source spatial reference system.
      `dst` - target spatial reference system.

      - `CreateCoordinateTransformation(org.gdal.osr.SpatialReference, org.gdal.osr.SpatialReference)`
