|
||
- 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.
