Method Details

bounds

public double[] bounds()

Description copied from interface: GeographicProjection

Indicates the minimum and maximum X and Y coordinates on the projected space.

Specified by:

bounds in interface GeographicProjection

Overrides:

bounds in class ProjectionTransform

Returns:

{minimum X, minimum Y, maximum X, maximum Y}

toGeo

public double[] toGeo(double x,
 double y)
               throws OutOfProjectionBoundsException

Description copied from interface: GeographicProjection

Converts map coordinates to geographic coordinates

Parameters:

x - - x map coordinate

y - - y map coordinate

Returns:

{longitude, latitude} in degrees

Throws:

OutOfProjectionBoundsException - if the specified point on the projected space cannot be mapped to a point of the geographic space

fromGeo

 double latitude)
                 throws OutOfProjectionBoundsException

Description copied from interface: GeographicProjection

Converts geographic coordinates to map coordinates

Parameters:

longitude - - longitude, in degrees

latitude - - latitude, in degrees

Returns:
