Interface ReferenceSystem

All Superinterfaces:

IdentifiedObject

All Known Subinterfaces:

CompoundCRS, CoordinateReferenceSystem, DerivedCRS, EngineeringCRS, GeneralDerivedCRS, GeocentricCRS, GeographicCRS, ImageCRS, ProjectedCRS, SingleCRS, SpatialReferenceSystemUsingGeographicIdentifier, TemporalCRS, VerticalCRS

@UML(identifier="RS_ReferenceSystem",
     specification=ISO_19115)
public interface ReferenceSystem
extends IdentifiedObject

Description of a spatial and temporal reference system used by a dataset.

Historical note: This interface was initially derived from an ISO 19111 specification published in 2003. Later revisions (in 2005) rely on an interface defined in ISO 19115 instead. The annotations were updated accordingly, but this interface is still defined in the referencing package (instead of metadata), the getValidArea() method still named that way and the getScope() method still defined here for this historical reason.

Since:

GeoAPI 1.0

Field Detail

VALID_AREA_KEY

static final java.lang.String VALID_AREA_KEY

Key for the "validArea" property to be given to the object factory createFoo(…) methods. This is used for setting the value to be returned by getValidArea().

See Also:

getValidArea(), Constant Field Values

SCOPE_KEY

static final java.lang.String SCOPE_KEY

Key for the "scope" property to be given to the object factory createFoo(…) methods. This is used for setting the value to be returned by getScope().

getScope(), Constant Field Values

Method Detail

getValidArea

@UML(identifier="domainOfValidity",
     obligation=OPTIONAL,
     specification=ISO_19115)
Extent getValidArea()

Area for which the (coordinate) reference system is valid.

Returns:

Coordinate reference system valid area, or null if not available.

getScope

@UML(identifier="SC_CRS.scope",
     obligation=OPTIONAL,
     specification=ISO_19111)
InternationalString getScope()

Description of domain of usage, or limitations of usage, for which this (coordinate) reference system object is valid.
