  Modifier and Type
  Class
  Description
  `class`
  `DefaultCompoundCRS`
  A CRS describing the position of points through two or more independent coordinate reference systems.

  `class`
  `DefaultEngineeringCRS`
  A 1-, 2- or 3-dimensional contextually local coordinate reference system.
  `class`
  `DefaultGeocentricCRS`
  A 2- or 3-dimensional coordinate reference system with the origin at the approximate centre of mass of the earth.
  `class`
  `DefaultGeographicCRS`
