      Specified by:
      getAxisUnit in interface org.opengis.referencing.datum.Ellipsoid
      Returns:
      the axis unit of measurement, which is assumed to be metres.

    • getSemiMajorAxis

      public double getSemiMajorAxis()
      Returns the equator radius of the PROJ4J implementation..
      Specified by:
      getSemiMajorAxis in interface org.opengis.referencing.datum.Ellipsoid
      Returns:
      the equator radius of the PROJ4J implementation

    • getInverseFlattening

      public double getInverseFlattening()
      Returns computes the inverse flatening from the equator and pole radius..
      Specified by:
      getInverseFlattening in interface org.opengis.referencing.datum.Ellipsoid
      Returns:
      computes the inverse flatening from the equator and pole radius

    • isIvfDefinitive

      public boolean isIvfDefinitive()
      Returns false since the inverse flatteing is computed..
      Specified by:
      isIvfDefinitive in interface org.opengis.referencing.datum.Ellipsoid
      Returns:

    • isSphere

      public boolean isSphere()
      Specified by:
      isSphere in interface org.opengis.referencing.datum.Ellipsoid
      Returns:
      whether the equator and pole radius are equal. Strict equality is okay because those values are set explicitly.
