CompoundCRS
coordinate reference system describing the position of points through two or more independent single coordinate reference systemsNote: two coordinate reference systems are independent of each other if coordinate values in one cannot be converted or transformed into coordinate values in the other.

CRS
coordinate reference system which is usually single but may be compound

true
DerivedCRS
single coordinate reference system that is defined through the application of a specified coordinate conversion to the definition of a previously established single coordinate reference system referred to as the base CRSNote: A derived coordinate reference system inherits its datum (or datum ensemble) from its base CRS. The coordinate conversion between the base and derived coordinate reference system is implemented using the parameters and formula(s) specified in the definition of the coordinate conversion.

DerivedEngineeringCRS
derived coordinate reference system which has an engineering coordinate reference system as its base CRS, thereby inheriting an engineering datum, and is associated with one of the coordinate system types within the engineeringCS class
http://standards.iso.org/iso/19111/ed-3/en/
DerivedGeodeticCRS
derived coordinate reference system which has either a geodetic or a geographic coordinate reference system as its base CRS, thereby inheriting a geodetic reference frame, and associated with a 3D Cartesian or spherical coordinate system
http://standards.iso.org/iso/19111/ed-3/en/
DerivedGeographicCRS
derived coordinate reference system which has either a geodetic or a geographic coordinate reference system as its base CRS, thereby inheriting a geodetic reference frame, and an ellipsoidal coordinate systemNote: A derived geographic CRS can be based on a geodetic CRS only if that geodetic CRS definition includes an ellipsoid.
http://standards.iso.org/iso/19111/ed-3/en/
DerivedParametricCRS
derived coordinate reference system which has a parametric coordinate reference system as its base CRS, thereby inheriting a parametric datum, and a parametric coordinate system
http://standards.iso.org/iso/19111/ed-3/en/
DerivedProjectedCRS
derived coordinate reference system which has a projected coordinate reference system as its base CRS, thereby inheriting a geodetic reference frame, but also inheriting the distortion characteristics of the base projected CRS

DerivedTemporalCRS
derived coordinate reference system which has a temporal coordinate reference system as its base CRS, thereby inheriting a temporal datum, and is associated with a temporal coordinate system
http://standards.iso.org/iso/19111/ed-3/en/
DerivedVerticalCRS
derived coordinate reference system which has a vertical coordinate reference system as its base CRS, thereby inheriting a vertical reference frame, and a vertical coordinate system
http://standards.iso.org/iso/19111/ed-3/en/
EngineeringCRS
contextually local coordinate reference system associated with an engineering datum and which is applied either to activities on or near the surface of the Earth without geodetic corrections, or on moving platforms such as road vehicles, vessels, aircraft or spacecraft, or as the internal CRS of an image

GeodeticCRS
coordinate reference system associated with a geodetic reference frame and a three-dimensional Cartesian or spherical coordinate systemNote: If the geodetic reference frame is dynamic then the geodetic CRS is dynamic, else it is static.

GeographicCRS
coordinate reference system associated with a geodetic reference frame and a two- or three-dimensional ellipsoidal coordinate system Note: If the geodetic reference frame is dynamic then the geographic CRS is dynamic, else it is static.
http://standards.iso.org/iso/19111/ed-3/en/

ParametricCRS
coordinate reference system having a parametric datum and a one-dimensional parametric coordinate system which uses parameter values or functions

1
ProjectedCRS
derived coordinate reference system which has a geodetic (usually geographic) coordinate reference system as its base CRS, thereby inheriting a geodetic reference frame, is converted using a map projection, and has a Cartesian coordinate system, usually two-dimensional but may be three-dimensionalNote: In the 3D case the base geographic CRSs ellipsoidal height is passed through unchanged and forms the vertical axis of the projected CRS's Cartesian coordinate system.

SingleCRS
coordinate reference system consisting of one coordinate system and either one datum or one datum ensemble

TemporalCRS
coordinate reference system associated with a temporal datum and a one-dimensional temporal coordinate system
http://standards.iso.org/iso/19111/ed-3/en/

1
VerticalCRS
coordinate reference system having a vertical reference frame and a one-dimensional vertical coordinate system used for recording gravity-related heights or depths; vertical CRSs make use of the direction of gravity to define the concept of height or depth, but the relationship with gravity may not be straightforward. Note 1: If the vertical reference frame is dynamic then the vertical CRS is dynamic, else it is static. Note 2: Ellipsoidal heights cannot be captured in a vertical coordinate reference system. They exist only as an inseparable part of a 3D coordinate tuple defined in a geographic 3D coordinate reference system.
