A coordinate system which sits inside another coordinate system. The fitted coordinate system
can be rotated and shifted, or use any other math transform to inject itself into the base
coordinate system.
An aggregate of two coordinate systems (CRS).
One of these is usually a CRS based on a two dimensional coordinate system
such as a geographic or a projected coordinate system with a horizontal
datum. The other is a vertical CRS which is a one-dimensional coordinate
system with a vertical datum.
A coordinate system which sits inside another coordinate system.
The fitted coordinate system can be rotated and shifted, or use any other
math transform to inject itself into the base coordinate system.
