    • getInstance

      public static EllipsoidMercator getInstance(double longitudeOrigin, double standardParallel, double scaleFactor, double falseEasting, double falseNorthing, double semiMajor, double semiMinor, double earthRadius, String units)
      Creates an object instance.
      Parameters:
      longitudeOrigin - the longitude of the origin or Double.NaN for the default (0.0).
      standardParallel - the standard parallel or Double.NaN for the default (0.0).
      scaleFactor - the scale factor or Double.NaN for the default (1.0). If both standardParallel and scaleFactor are speficied, standardParallel takes precedence.
      falseEasting - the false easting or Double.NaN for the default (0.0).
      falseNorthing - the false northing or Double.NaN for the default (0.0).
      semiMajor - the semi-major axis of the ellipsoid in meters or Double.NaN for a sphere.
      semiMinor - the semi-minor axis of the ellipsoid in meters or Double.NaN for a sphere.
      earthRadius - the earth radius for the sphere in meters or Double.NaN for an ellipsoid. If not specified, the semi-major and semi-minor axes must be specified.
      units - the units to use for XY projection point coordinate values.
      Returns:
      the instance of the Mercator projection object.
