Method Detail

project

public ProjCoordinate project(double lplam,
                              double lpphi,
                              ProjCoordinate out)

Description copied from class: Projection

Computes the projection of a given point (i.e. from geographics to projection space). This should be overridden for all projections.

Overrides:

project in class Projection

Parameters:

lplam - the geographic x ordinate (in radians)

lpphi - the geographic y ordinatee (in radians)

out - the projected coordinate (in coordinate system units)

Returns:

the target coordinate

initialize

public void initialize()

Description copied from class: Projection

Initialize the projection. This should be called after setting parameters and before using the projection. This is for performance reasons as initialization may be expensive.

Overrides:

initialize in class Projection

hasInverse

public boolean hasInverse()

Description copied from class: Projection

Tests whether this projection has an inverse. If this method returns true then the Projection.inverseProject(ProjCoordinate, ProjCoordinate) and Projection.inverseProjectRadians(ProjCoordinate, ProjCoordinate) methods will return meaningful results.

Overrides:

hasInverse in class Projection

Returns:

true if this projection has an inverse

toString

public java.lang.String toString()

Overrides:

toString in class PseudoCylindricalProjection

equals

public boolean equals(java.lang.Object that)

Description copied from class: Projection

Represents quality between possible outputs of Projection.project(ProjCoordinate, ProjCoordinate). Subclasses of Projection should capture additional state that is used in the project method and delgate to base. Note: The name of the projection is not part of equality.

Overrides:

equals in class Projection

hashCode

public int hashCode()

Description copied from class: Projection

Hash of those fields considered in Projection equalituy. Subclasses that override equality should override hashCode.

Overrides:

hashCode in class Projection
