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

The root class for this package is AbstractCRS
.
Coordinate Reference System (CRS) can have various number of dimensions, but some restrictions
apply depending on the CRS type:
Dimension | CRS type examples | Remarks |
---|---|---|
3 | Geographic, Geocentric | ISO 19111 uses the same class, GeodeticCRS , for those two cases. |
2 | Geographic, Projected | GeographicCRS can also be 3D. |
1 | Vertical, Temporal. | |
Any | Compound | Often used for adding a time axis to the above CRS. |

type. OGC/ISO distinguishes the geographic/geocentric cases according the type
of the coordinate system associated to that CRS:
