  • Method Details

    • defaultDatum

      public Datum defaultDatum()
      Description copied from class: CoordinateSystem
      Get the defaul Datum for an instance of CoordinateSystem. For example, instances of OSGB usually use the OSGB 1936 datum.
      Specified by:
      defaultDatum in class CoordinateSystem
      Returns:
      The default Datum used by this instance of CoordinateSystem
    • defaultEllipsoid

      public Ellipsoid defaultEllipsoid()
      Description copied from class: CoordinateSystem
      The default Ellipsoid used by instances of this CoordinateSystem For example, a CoordinateSystem of type OSGB has the AirySphere as its default Ellipsoid
      Specified by:
      defaultEllipsoid in class CoordinateSystem
      Returns:
      The Ellipsoid used as the deafult for this CoordinateSystem
    • toString

      public String toString()
      Provide a String representation of this UTM point in UTM coordinates
      Specified by:
      toString in class CoordinateSystem
      Returns:
      A UTM coordinate String
    • f0

      public double f0()
      The scale factor on the Central Meridian. Generally, Transverse Mercator projections increasingly exaggerate distances further from the central meridian. It is usual to reduce the scale factor at the central meridian to compensate for this effect and optimise the scale over the area of interest.
      Specified by:
      f0 in class TransverseMercator
      Returns:
      the value of the ScaleFactor at the central meridian.
    • n0

      public double n0()
      n0() defines the "false northing" distance of the projection. False origins are usually used with TM projections to ensure that easting and northing distances are always positive over the area of interest. n0() is used as an offset to the grid so that the "true origin" appears to have a northing value equal to n0().
      Specified by:
      n0 in class TransverseMercator
      Returns:
      The false northing distance (double)
    • phi0

      public double phi0()
      phi0() defines the latitude of the true origin of the projection. Note, however, that many Transverse Mercator projections employ a false origin. See n0() and e0() .
      Specified by:
      phi0 in class TransverseMercator
      Returns:
      The latitude of the true origin (radians)
