Vertical Offshore Reference Frames.

Vertical Offshore Reference Frames (VORF)

The Vertical Offshore Reference Frames (VORF) research project is an ongoing collaboration between University College London and the United Kingdom Hydrographic Office (UKHO).  It commenced in 2005 with the aim of providing the ability to transform vertical height information in the coastal and offshore zones between reference levels such as:

  • Chart Datum (the reference level for nautical charts)
  • Mean Sea Level
  • Lowest Astronomical Tide
  • Mean Low Water Springs
  • European Terrestrial Reference Frame (ETRF89)
  • Ordnance Datum (Newlyn)
  • Ordnance Datum (Poolbeg)

The VORF solution for UK and Ireland was completed in 2008 and has become an essential tool in operational hydrography.  Current focus is on extending the concept globally for the offshore zone beyond 12 nautical miles from land.
