Method Detail

toReference

public double[][] toReference(double[][] tuples)
                       throws VisADException

convert from x,y to lat,lon

Specified by:

toReference in class CoordinateSystem

Parameters:

tuples - contains the x,y coordinates (grid col, row)

Returns:

tuple of (lat,lon);

Throws:

VisADException - if problem with conversion.

fromReference

public double[][] fromReference(double[][] tuples)
                         throws VisADException

convert from lat,lon to x,y

Specified by:

fromReference in class CoordinateSystem

Parameters:

tuples - contains the lat,lon coordinates

Returns:

array of double values in CoordinateSystem Units.

Throws:

VisADException - if problem with conversion.

equals

public boolean equals(Object cs)

determine if the Coordinate System in question is an EASECoordinateSystem

Specified by:

equals in class CoordinateSystem

Parameters:

cs - the object in question.

Returns:

true if and only if this instance equals cs.

getDefaultMapArea

public Rectangle2D getDefaultMapArea()

return the bounding box for this projection

Specified by:

getDefaultMapArea in class MapProjection

Returns:

the bounding box of the MapProjection

getAspectRatio

public double getAspectRatio()

return the ratio of the grid spacing between rows and columns

main
