BathyElli v2.1 HAT surface
The BathyElli v2.1 HAT surface is a realisation of the ellipsoidal height of the Highest Astronomical Tide (HAT).
The HAT realised by the BathyElli v2.1 HAT surface is expressed at the reference date of 2000/01/01.
The HAT realised by the BathyElli v2.1 HAT surface is expressed by its ellipsoidal height in the legal geodetic datum according to the decrees n°2000-1276 and 2006-272. For metropolitan France, the legal geodetic datum is RGF93 v2 and the associated ellipsoid GRS80.
The difference between RGF93 v2 and the latest realisation of ITRS or the latest realisation of WGS84 is less than a few meters. For applications that do not require an uncertainty of better than a few metres on the horizontal, no change of realisation of the geodetic system is necessary.
This product covers the intersection between the Shom tidal model and the different tidal zones of metropolitan France.
