public McBrydeThomasFlatPolarQuarticProjection()

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

projectInverse

public ProjCoordinate projectInverse(double xyx,
                                     double xyy,
                                     ProjCoordinate out)

Description copied from class: Projection

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

Overrides:

projectInverse in class Projection

Parameters:

xyx - the projected x ordinate (in coordinate system units)

xyy - the projected y ordinate (in coordinate system units)

out - the inverse-projected geographic coordinate (in radians)

Returns:

the target coordinate

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

isEqualArea

public boolean isEqualArea()

Description copied from class: Projection

Tests whether this projection is equal-area An equal-area projection preserves relative sizes of projected areas.

Overrides:

isEqualArea in class Projection

Returns:

true if this projection is equal-area

toString

public java.lang.String toString()

Overrides:

toString in class PseudoCylindricalProjection
