AbstractIdentifiedObject

AbstractDatum

DefaultEngineeringDatum

All Implemented Interfaces:

Serializable, Datum, EngineeringDatum, IdentifiedObject

public class DefaultEngineeringDatum
extends AbstractDatum
implements EngineeringDatum

Defines the origin of an engineering coordinate reference system. An engineering datum is used in a region around that origin. This origin can be fixed with respect to the earth (such as a defined point at a construction site), or be a defined point on a moving vehicle (such as on a ship or satellite).

Field Details

UNKNOWN

public static final DefaultEngineeringDatum UNKNOWN

An engineering datum for unknown coordinate reference system. Such CRS are usually assumed cartesian, but will not have any transformation path to other CRS.

• DefaultEngineeringCRS.CARTESIAN_2D
• DefaultEngineeringCRS.CARTESIAN_3D

Constructor Details

DefaultEngineeringDatum

public DefaultEngineeringDatum(EngineeringDatum datum)

Constructs a new datum with the same values than the specified one. This copy constructor provides a way to wrap an arbitrary implementation into a Geotools one or a user-defined one (as a subclass), usually in order to leverage some implementation-specific API. This constructor performs a shallow copy, i.e. the properties are not cloned.

Since:

2.2

DefaultEngineeringDatum

public DefaultEngineeringDatum(String name)

Constructs an engineering datum from a name.

Parameters:

name - The datum name.

DefaultEngineeringDatum

public DefaultEngineeringDatum(Map<String,?> properties)

Constructs an engineering datum from a set of properties. The properties map is given unchanged to the super-class constructor.

Parameters:

properties - Set of properties. Should contains at least "name".

Method Details

equals

public boolean equals(AbstractIdentifiedObject object,
 boolean compareMetadata)

Compare this datum with the specified object for equality.

Overrides:

equals in class AbstractDatum

Parameters:

object - The object to compare to this.

compareMetadata - true for performing a strict comparaison, or false for comparing only properties relevant to transformations.

Returns:

true if both objects are equal.

formatWKT

protected String formatWKT(Formatter formatter)

Format the inner part of a Well Known Text (WKT) element.

Overrides:

formatWKT in class AbstractDatum

Parameters:

formatter - The formatter to use.

Returns:

The WKT element name, which is "LOCAL_DATUM"
