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

    Subclasses of AbstractCRS in org.apache.sis.referencing.crs
    Modifier and Type | Class | 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 | Description
