+- coordinate systems
+  - reference ellipsoid/datum
+    - can have multiple coordinate systems
+	- WGS84 datum -> GPS/
+	- reference ellipsoid -> WGS84/OSGB36 = datum (geodetic)
+	GRS80 ellipsoid )reference ellipsoid)
+	- OS -> OSGB36 datum/Airy 1830 ellipsoid
+	  - Transverse Mercator projection with an origin at 49° N, 2° W 
+	  - The most common transformation is called the Helmert datum transformation, which results in a typical 7 m error from true. The definitive transformation from ETRS89 that is published by the OSGB is called the National Grid Transformation OSTN02.[2] This models the detailed distortions in the 1936–1962 retriangulation, and achieves backwards compatibility in grid coordinates to sub-metre accuracy.
