## Uses of Interface
org.opengis.referencing.ReferenceSystem

Packages that use ReferenceSystem
org.opengis.metadata: Root package for metadata.
org.opengis.metadata.lineage: Lineage information.
org.opengis.referencing: Reference systems.
org.opengis.referencing.crs: Coordinate reference systems (coordinate systems with a datum).
org.opengis.temporal

Uses of ReferenceSystem in org.opengis.metadata

Methods in org.opengis.metadata that return types with arguments of type ReferenceSystem
`Collection<? extends ReferenceSystem>` `MetaData.getReferenceSystemInfo()` Description of the spatial and temporal reference systems used in the dataset.

Uses of ReferenceSystem in org.opengis.metadata.lineage

Methods in org.opengis.metadata.lineage that return ReferenceSystem
`ReferenceSystem` `Source.getSourceReferenceSystem()` Spatial reference system used by the source data.

Uses of ReferenceSystem in org.opengis.referencing

Subinterfaces of ReferenceSystem in org.opengis.referencing
`interface` `SpatialReferenceSystemUsingGeographicIdentifier` Spatial reference system using geographic identifier, a reference to a feature with a known spatial location.

Uses of ReferenceSystem in org.opengis.referencing.crs

Subinterfaces of ReferenceSystem in org.opengis.referencing.crs
`interface` `CompoundCRS` A coordinate reference system describing the position of points through two or more independent coordinate reference systems.
`interface` `CoordinateReferenceSystem` Abstract coordinate reference system, usually defined by a coordinate system and a datum.
`interface` `DerivedCRS` A coordinate reference system that is defined by its coordinate conversion from another coordinate reference system but is not a projected coordinate reference system.
`interface` `EngineeringCRS` A contextually local coordinate reference system.
`interface` `GeneralDerivedCRS` A coordinate reference system that is defined by its coordinate conversion from another coordinate reference system (not by a datum).
`interface` `GeocentricCRS` A 3D coordinate reference system with the origin at the approximate centre of mass of the earth.
`interface` `GeodeticCRS` A coordinate reference system associated with a geodetic datum.
`interface` `GeographicCRS` A coordinate reference system based on an ellipsoidal approximation of the geoid; this provides an accurate representation of the geometry of geographic features for a large portion of the earth's surface.
`interface` `ImageCRS` An engineering coordinate reference system applied to locations in images.
`interface` `ProjectedCRS` A 2D coordinate reference system used to approximate the shape of the earth on a planar surface.
`interface` `SingleCRS` Abstract coordinate reference system, consisting of a single Coordinate System and a single Datum (as opposed to Compound CRS).
`interface` `TemporalCRS` A 1D coordinate reference system used for the recording of time.
`interface` `VerticalCRS` A 1D coordinate reference system used for recording heights or depths.

Uses of ReferenceSystem in org.opengis.temporal

Subinterfaces of ReferenceSystem in org.opengis.temporal
`interface` `Calendar` A discrete temporal reference system that provides a basis for defining temporal position to a resolution of one day.
`interface` `Clock` Provides a basis for defining temporal position within a day.
`interface` `OrdinalReferenceSystem` Provides only the attributes inherited from temporal reference system.
`interface` `TemporalCoordinateSystem` A temporal coordinate system to simplify the computation of temporal distances between points and the functional description of temporal operations.
`interface` `TemporalReferenceSystem` Provides information about a temporal reference system.
