| | PolarStereographic(ParameterValueGroup parameters, ParameterDescriptorGroup descriptor, Boolean forceSouthPole)
Constructs a polar stereographic projection.
Parameters:
parameters - The group of parameter values.
Parameters:
descriptor - The expected parameter descriptor.
Parameters:
forceSouthPole - Forces projection to North pole if Boolean.FALSE,to South pole if Boolean.TRUE, or do not force (i.e. |
| Method Summary | |
| public boolean | equals(Object object)
Compares the specified object with this map projection for equality. | | public ParameterValueGroup | getParameterValues()
| | public int | hashCode()
Returns a hash value for this map projection. | | protected Point2D | inverseTransformNormalized(double x, double y, Point2D ptDst)
Transforms the specified (x,y) coordinates (units in radians)
and stores the result in
ptDst (linear distance on a unit sphere). | | protected Point2D | transformNormalized(double x, double y, Point2D ptDst)
Transforms the specified (λ,φ) coordinates
(units in radians) and stores the result in
ptDst (linear distance
on a unit sphere). |

| PolarStereographic | | PolarStereographic(ParameterValueGroup parameters, ParameterDescriptorGroup descriptor, Boolean forceSouthPole) throws ParameterNotFoundException(Code) | | Constructs a polar stereographic projection.
Parameters:
parameters - The group of parameter values.
Parameters:
descriptor - The expected parameter descriptor.
Parameters:
forceSouthPole - Forces projection to North pole if Boolean.FALSE,to South pole if Boolean.TRUE, or do not force (i.e. detectfrom other parameter values) if null .
throws:
ParameterNotFoundException - if a required parameter was not found. |
