      • transformNormalized

        protected Point2D transformNormalized​(double x,
                                              double y,
                                              Point2D ptDst)
                                       throws ProjectionException
        Transforms the specified (λ,φ) coordinates (units in radians) and stores the result in ptDst (linear distance on a unit sphere).
        Parameters:
        x - The longitude of the coordinate, in radians.
        y - The latitude of the coordinate, in radians.
        ptDst - the specified coordinate point that stores the result of transforming ptSrc, or null. Ordinates will be in a dimensionless unit, as a linear distance on a unit sphere or ellipse.
        Returns:
        the coordinate point after transforming (lambda, phi) and storing the result in ptDst.
        Throws:
        ProjectionException - if the point can't be transformed.
      • inverseTransformNormalized

        protected Point2D inverseTransformNormalized​(double x,
                                                     double y,
                                                     Point2D ptDst)
                                              throws ProjectionException
        Transforms the specified (x,y) coordinates and stores the result in ptDst.
        Specified by:
        inverseTransformNormalized in class MapProjection
        Parameters:
        x - The easting of the coordinate, linear distance on a unit sphere or ellipse.
        y - The northing of the coordinate, linear distance on a unit sphere or ellipse.
        ptDst - the specified coordinate point that stores the result of transforming ptSrc, or null. Ordinates will be in radians.
        Returns:
        the coordinate point after transforming x, y and storing the result in ptDst.
        Throws:
        ProjectionException - if the point can't be transformed.
      • getToleranceForAssertions

        protected double getToleranceForAssertions​(double longitude,
                                                   double latitude)
        Maximal error (in metres) tolerated for assertions, if enabled.
        Overrides:
        getToleranceForAssertions in class MapProjection
        Parameters:
        longitude - The longitude in decimal degrees.
        latitude - The latitude in decimal degrees.
        Returns:
        The tolerance level for assertions, in meters.
