This dataset provides an index to the Electronic Navigational Charts (ENC) available through the LINZ Data Service showing extent and ENC attributes.
The ENC index is compiled from the S-57 Object Class “Nautical publication information” which is used to relate additional nautical information or publications to the data. The attributes are populated by Land Information New Zealand’s (LINZ) production database.
S-57 is a standard used to exchange digital hydrographic data between hydrographic offices and to distribute this data to users. This dataset was compiled for the use in the scale ranges 1:1,000 to 1:1,500,000 and smaller.
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 ENCs, published and maintained by the New Zealand Hydrographic Authority at LINZ. Refer to the following link for information about S-57 data: http://www.linz.govt.nz/hydro/regulation/
This document provides detailed metadata for the NZ Electronic Navigational Chart (ENC) and Paper Nautical Chart indexes available on the LINZ Data Service: https://data.linz.govt.nz/document/21520-enc-and-paper-chart-indexes-dictionary/
The hydrographic data available through the LINZ Data Service is based on official Electronic Navigational Charts (ENCs) published and maintained by the New Zealand Hydrographic Authority.
Prior to loading onto this service, the S-57 data from these ENCs is converted to a PostgreSQL table.
