getParameterDescriptors
Returns the parameter descriptors for this map projection. This is used for a providing a default implementation ofMapProjection.getParameterValues()
, as well as arguments checking.- Specified by:
getParameterDescriptors
in classMapProjection
- Returns:
- The parameter descriptors for this math transform, or
null
. - See Also:
-
getParameterValues
Returns the parameter values for this map projection.- Overrides:
getParameterValues
in classMapProjection
- Returns:
- A copy of the parameter values for this map projection.

transformNormalized
protected Point2D transformNormalized(double lam, double phi, Point2D xy) throws ProjectionException Transforms the specified (λ,φ) coordinates (units in radians) and stores the result inxy
(linear distance on a unit sphere).- Specified by:
transformNormalized
in classMapProjection
- Parameters:
lam
- The longitude of the coordinate, in radians.phi
- The latitude of the coordinate, in radians.xy
- 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 lp) throws ProjectionException Transforms the specified (x,y) coordinates and stores the result inlp
.- 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.lp
- 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.
