Method Detail

Name

public String Name()

Overrides:

Name in class Projection

to_World

public Point2D.Double to_World(Point2D image_coordinate)
                        throws IllegalArgumentException

Get the world longitude,latitude coordinate for an image sample,line coordinate.

The conversion algorithm is:

longitude = Center_Longitude + x / (R * cos (Center_Latitude))
latitude = y / R

where R is the radius of the body at the Center_Latitude.

Overrides:

to_World in class Projection

Parameters:

image_coordinate - The image sample,line coordinate.

Returns:

The world longitude,latitude coordinate. The x value of the coordinate Point2D is the longitude; the y value is the latitude. Values are in degrees within the range 0-360.

Throws:

IllegalArgumentException

to_Image

public Point to_Image(Point2D world_coordinate)
               throws IllegalArgumentException

Get the image sample,line coordinate for a world longitude,latitude coordinate.

The conversion algorithm is:

Overrides:

to_Image in class Projection

Parameters:

world_coordinate - The world longitude,latitude coordinate. The x value of the coordinate Point2D is the longitude; the y value is the latitude. Values are in degrees.

Returns:

The image sample,line coordinate.

Throws:

IllegalArgumentException
