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 inptDst
(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 transformingptSrc
, ornull
. 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 inptDst
. - 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 inptDst
.- Specified by:
inverseTransformNormalized
in classMapProjection
- 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 transformingptSrc
, ornull
. Ordinates will be in radians.- Returns:
- the coordinate point after transforming
x
,y
and storing the result inptDst
. - 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 classMapProjection
- Parameters:
longitude
- The longitude in decimal degrees.latitude
- The latitude in decimal degrees.- Returns:
- The tolerance level for assertions, in meters.
