Method Detail

initializeImp

protected void initializeImp()

Specified by:

initializeImp in class StandardProjection

project

public void project(Point point)

Description copied from class: Projection

Project from latlong to xy. Modifies the input Point. Remember that Point.x is longitude, Point.y is latitude.

Specified by:

project in class Projection

reverse

public void reverse(Point point)

Description copied from class: Projection

Reverse project from xy to latlong. Results are returned with point.x = long, point.y = lat. Modifies input.

Specified by:

reverse in class Projection

getStandardLatitude1

public double getStandardLatitude1()

First (North) standard latitude.

setStandardLatitude1

public void setStandardLatitude1(double newStandardLatitude1)

First (North) standard latitude.

getStandardLatitude2

public double getStandardLatitude2()

Second (South) standard latitude.

setStandardLatitude2

public void setStandardLatitude2(double newStandardLatitude2)

Second (South) standard latitude.
