Class IlvGeocentricCoordinateSystem

java.lang.Object
  ilog.views.maps.srs.coordsys.IlvCoordinateSystem
      ilog.views.maps.srs.coordsys.IlvGeocentricCoordinateSystem

All Implemented Interfaces:

IlvPersistentObject

public class IlvGeocentricCoordinateSystem
extends IlvCoordinateSystem

The geocentric coordinate system.
This coordinate system is a three-dimensional Cartesian system with the x-axis positive towards the Greenwich meridian and equator, the y-axis through the intersection of the equator with longitude 90 degrees East, and the z-axis corresponding to the polar axis and positive northwards.

Since:

JViews 5.0

Field Detail

KERNEL

public static final IlvGeocentricCoordinateSystem KERNEL

The default geocentric coordinate system, with units in meters and the WGS84 datum.

Constructor Detail

IlvGeocentricCoordinateSystem

public IlvGeocentricCoordinateSystem(String name,
                                     IlvLinearUnit unit,
                                     IlvHorizontalDatum datum)

Constructs a new geocentric coordinate system.
The datum parameter specifies a datum whose ellipsoid is not used. Only the datum shifts are significant.

Parameters:

name - The name of the coordinate system.

unit - The linear unit of the coordinate system.

datum - The datum for the coordinate system.

IlvGeocentricCoordinateSystem

public IlvGeocentricCoordinateSystem(IlvGeocentricCoordinateSystem source)

Constructs a new IlvCoordinateSystem by copying an existing one.

Parameters:

source - The source coordinate system.

IlvGeocentricCoordinateSystem

public IlvGeocentricCoordinateSystem(IlvInputStream stream)
                              throws IlvReadFileException

Reads the object from an IlvInputStream object.

Parameters:

stream - The input stream.

Throws:

IlvReadFileException - If the format is not correct.

Method Detail

write

public void write(IlvOutputStream stream)
           throws IOException

Writes the object to the specified IlvOutputStream.

Specified by:

write in interface IlvPersistentObject

Overrides:

write in class IlvCoordinateSystem

Parameters:

stream - The stream to write this unit to.

Throws:

IOException - If an I/O error occurs.

copy

public IlvCoordinateSystem copy()

Returns a copy of this coordinate system.

Specified by:

copy in class IlvCoordinateSystem

getLinearUnit

public IlvLinearUnit getLinearUnit()

Returns the linear unit.

getHorizontalDatum

public IlvHorizontalDatum getHorizontalDatum()

Returns the horizontal datum of this geocentric coordinate system.

toString

public String toString()

Returns a string representation for this coordinate system. The string representation of this coordinate system is "geocentric(unit)" where unit is the linear unit of this coordinate system.

Overrides:

toString in class Object

equals

public boolean equals(Object other)

Returns true if this coordinate system is equal to the specified coordinate system.

Overrides:

equals in class IlvCoordinateSystem
