This specification is provided as the authoritative reference for the maintenance of New Zealand’s source data, and is to be used as a supplement to the IHO publication “S-57 Appendix B.1 Annex A – Use of the Object Catalogue for ENC” (UOC).

This specification has three purposes:

  1. To clarify where necessary and provide additional guidance where an IHO specification may not be mandatory.
  2. To expand those clauses in the UOC which are left open to national discretion and require further definition
  3. To ensure a seamless data coverage in regards to horizontal and vertical consistency.

Unless otherwise specified in this document the UOC will be followed.
