Constructor Detail

IlvAbstractARCProjection

protected IlvAbstractARCProjection()

Default constructor of the abstract projection. This should not be used in any user application.

Parameters:

d - New value of ASZ.

setBs

public void setBs(double d)

sets BS parameter.

Parameters:

d - New value of BS.

setLam0

public void setLam0(double d)

sets Lambda0 parameter.

Parameters:

d - New value of Lambda 0.

setPhi0

public void setPhi0(double d)

sets Phi0 parameter.

Parameters:

d - New value of Phi0.

Sets Zone number.

Parameters:

z - The new zone.

sForward

protected void sForward(IlvCoordinate ll)
                 throws IlvToleranceConditionException

Implements the projection for a sphere.

This protected method should be implemented by the classes that extend the class IlvProjection. It is not called directly by the user, but by the IlvProjection.forward method if the ellipsoid associated with the projection is a sphere.

The method should convert the ll parameter to the projected coordinates. The various parameters associated with a projection, such as the measurement unit, the false easting or the central meridian, must not be taken into account in this method because they are processed by the calling method IlvProjection.forward. In this method, the sphere is assumed to be of radius 1.

Specified by:

sForward in class IlvProjection

Parameters:

ll - Longitude/latitude coordinates in radians.

Throws:

IlvToleranceConditionException - If the values are not within the tolerated limits.
