- - ### Uses of AbstractCRS in org.apache.sis.referencing.crs

    Subclasses of AbstractCRS in org.apache.sis.referencing.crs
    Modifier and Type | Class and Description
    --- | ---
    `class` | `DefaultCompoundCRS` A CRS describing the position of points through two or more independent coordinate reference systems.
    `class` | `DefaultDerivedCRS` A coordinate reference system that is defined by its coordinate conversion from another CRS (not by a datum).
    `class` | `DefaultEngineeringCRS` A 1-, 2- or 3-dimensional contextually local coordinate reference system.
    `class` | `DefaultGeocentricCRS` A 3-dimensional coordinate reference system with the origin at the approximate centre of mass of the earth.
    `class` | `DefaultGeographicCRS` A 2- or 3-dimensional coordinate reference system based on an ellipsoidal approximation of the geoid.
    `class` | `DefaultImageCRS` A 2-dimensional engineering coordinate reference system applied to locations in images.
    `class` | `DefaultParametricCRS` A 1-dimensional coordinate reference system which uses parameter values or functions.
    `class` | `DefaultProjectedCRS` A 2-dimensional coordinate reference system used to approximate the shape of the earth on a planar surface.
    `class` | `DefaultTemporalCRS` A 1-dimensional coordinate reference system used for the recording of time.
    `class` | `DefaultVerticalCRS` A 1-dimensional coordinate reference system used for recording heights or depths.

    Methods in org.apache.sis.referencing.crs that return AbstractCRS
    Modifier and Type | Method and Description
    --- | ---
    `static AbstractCRS` | AbstractCRS.`castOrCopy(CoordinateReferenceSystem object)` Returns a SIS coordinate reference system implementation with the values of the given arbitrary implementation.
    `AbstractCRS` | AbstractCRS.`forConvention(AxesConvention convention)` Returns a coordinate reference system equivalent to this one but with axes rearranged according the given convention.
