    • CRS-GCENCRS (Geocentric coordinate systems)
    • CRS-VERTCRS (Vertical coordinate systems)
    • CRS-ENGCRS (Engineering coordinate systems)
    • CRS-COMPOUNDCRS (Compound coordinate systems)
    • CRS-DRVDCRS (Derived coordinate systems)
  • COORDOP (All operations)
    • COORDOP-COPTRAN (Transformations)
    • COORDOP-COPCONO (Compound operations)
    • COORDOP-POIMOTO (Point motion operations)
    • COORDOP-COPCON (Conversions)
  • DATUM (All datums)
    • DATUM-VERTDAT (Vertical datums)
    • DATUM-ENGDAT (Engineering datums)
    • DATUM-GEODDAT (Geodetic datums)
    • DATUM-DYNGEODDA (Dynamic geodetic datums)
    • DATUM-ENSEMDAT (Ensemble datum)

    • CS-VERTCS (Vertical coordinate system)
    • CS-SPHERCS (Spherical coordinate system)
    • CS-CARTESCS (Cartesian coordinate system)
    • CS-ELLIPCS (Ellipsoidal coordinate system)
    • CS-AFFINE (Affine coordinate system)
    • CS-ORDINAL (Ordinal coordinate system)
