Method Details

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

getHeightOfOrbit

public double getHeightOfOrbit()

Description copied from class: Projection

Get height of orbit - Geostationary satellite projection

Overrides:

getHeightOfOrbit in class Projection

Returns:

Height of orbit

setHeightOfOrbit

public void setHeightOfOrbit(double h)

Description copied from class: Projection

Set height of orbit - Geostationary satellite projection

Overrides:

setHeightOfOrbit in class Projection

Parameters:

h - Height of orbit

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

project_s

public void project_s(double lplam,
 double lpphi,
 ProjCoordinate out)

project_e

public void project_e(double lplam,
 double lpphi,
 ProjCoordinate out)

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

projectInverse_s

public void projectInverse_s(double xyx,
 double xyy,
 ProjCoordinate out)

projectInverse_e

public void projectInverse_e(double xyx,
 double xyy,
 ProjCoordinate out)

isEqualArea

public boolean isEqualArea()

Returns true if this projection is equal area

Overrides:

isEqualArea in class Projection

Returns:

true if this projection is equal-area

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 String toString()

Overrides:

toString in class Projection

equals

public boolean equals(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
