- /// axes, units and datum then client code is permitted to assume that the two coordinate
- /// systems are identical. This allows several datasets from a common source (e.g. a CAD
- /// system) to be overlaid. In addition, some implementations of the Coordinate
- /// Transformation (CT) package may have a mechanism for correlating local datums. (E.g.
- /// from a database of transformations, which is created and maintained from real-world
