A new feature specified by the IMO and that affects safety of navigation which cannot adequately be encoded by any existing object class for use in an S-57 data set. Details of the specific object class type can be found in the field "inform".

S-57 Object Class: New object

S-57 Acronym: NEWOBJ

This data was compiled for the use in the scale range 1:4,000 to 1:22,000.

THIS DATA DOES NOT REPLACE NAUTICAL CHARTS AND MUST NOT BE USED FOR NAVIGATION.

This data is based on the S-57 data format used in Electronic Navigational Charts (ENCs) published and maintained by the New Zealand Hydrographic Authority at Toitū Te Whenua Land Information New Zealand (LINZ).
