Package com.luciad.geodesy

Class TLcdGenericGeodeticDatumFactory

java.lang.Object

com.luciad.geodesy.TLcdGenericGeodeticDatumFactory

All Implemented Interfaces:

ILcdGeodeticDatumFactory, Serializable

public class TLcdGenericGeodeticDatumFactory
extends Object
implements ILcdGeodeticDatumFactory, Serializable

ILcdGeodeticDatumFactory implementation that creates TLcdGeodeticDatum objects based on the 7 (or 10) parameters that define the geodetic datum.

The properties read are:

Property name	Default value
x	0
y	0
z	0
rotx	0
roty	0
rotz	0
scale	1.0
px	0.0
py	0.0
pz	0.0
name	Geodetic datum

The geodetic datum is based on an ellipsoid, which is defined by two additional properties:

Property name	Default value
a	--
1overf	--

The TLcdGeodeticDatum generated has WGS84 as a reference datum.

Method Details

createGeodeticDatum

public ILcdGeodeticDatum createGeodeticDatum(String aPrefix,
 Properties aProperties)
                                      throws IllegalArgumentException

Creates a TLcdGeodeticDatum which has the WGS84 geodetic datum as reference datum and retrieves its parameters from the properties object.

Specified by:

createGeodeticDatum in interface ILcdGeodeticDatumFactory

Parameters:

aPrefix - the prefix to pre-pend to the properties to be read.

aProperties - the Properties object to retrieve the geodetic datum from.

Returns:

a TLcdGeodeticDatum which has the WGS84 geodetic datum as reference datum and its parameters retrieved from the properties object.

Throws:

IllegalArgumentException - when a property which is expected as double could not be converted to a double.

writePropertiesSFCT

public void writePropertiesSFCT(ILcdGeodeticDatum aGeodeticDatum,
 String aPrefix,
 Properties aPropertiesSFCT)

If the geodetic datum passed is a TLcdGeodeticDatum instance with WGS84 as its reference datum, this method adds the parameters of the geodetic datum to the Properties object, so that the geodetic datum can be recreated with createGeodeticDatum(java.lang.String, java.util.Properties).

Parameters:

aGeodeticDatum - the TLcdGeodeticDatum to add to the properties object.

aPrefix - the prefix to pre-pend to the properties names.

aPropertiesSFCT - the Properties object to modify.

Throws:

IllegalArgumentException - when an ILcdGeodeticDatum implementation other than TLcdGeodeticDatum is passed, or a TLcdGeodeticDatum with a reference datum different from WGS84.

canExportGeodeticDatum

public boolean canExportGeodeticDatum(ILcdGeodeticDatum aGeodeticDatum)

Returns whether the passed geodetic datum can be exported.

Parameters:

aGeodeticDatum - the geodetic datum to check.

Returns:

true if the geodetic datum passed is a TLcdGeodeticDatum, with WGS84 as the reference datum.
