VORF meaning in General ?

Answer» What is Vertical Offshore Reference Frames mean?

Vertical Offshore Reference Frames (VORF) is a set of high resolution surfaces which together define the vertical datum for hydrographic surveying and charting in the United Kingdom and Ireland. The following surfaces are included:

Chart Datum (CD)Lowest Astronomical Tide (LAT)Mean Sea Level (MSL)Mean Low Water Springs (MLWS)Mean High Water Springs (MHWS)Highest Astronomical Tide (HAT)Land datums including Ordnance Datums Newlyn, Belfast and Poolbeg

All the surfaces are modelled with respect to the terrestrial reference frame used for satellite navigation (GNSS) positioning, ETRS89. Thus VORF directly permits the use of high precision GNSS in hydrographic survey, and also allows the capability of transforming vertical data between the different datums.
