1 Scope

GB 12319-2022 is the Chinese national standard on symbols, abbreviations and terms used on chinese charts, in the field of natural and applied sciences. It carries no /T suffix, which in the Chinese system means compliance is mandatory: a product or a practice within its scope has to meet it to be lawfully made, sold or carried out in China. It was issued on 13 July 2022 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 August 2023. Classification: ICS 07.040, CCS A79. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This document specifies the symbols, annotations and outline decoration of various elements represented on Chinese nautical charts, as well as the methods and methods of using these symbols. Require. This document is suitable for surveying, producing and publishing charts of various scales.

3 Terms and Definitions

The following terms and definitions apply to this document.

3.1 depth benchmark soundingdatum The depth starting surface of the water depth indicated on the chart.

Note. The "theoretical lowest tide level" is generally used as the depth benchmark in the coastal areas of China.

3.2 height datum heightdatum The starting surface of the ground point elevation.

Note. China's coastal areas generally use the "1985 National Elevation Datum" as the elevation datum.

3.3 water depth soundings The vertical distance from the depth reference to the bottom.

Note. The water depth value is in meters (m).

3.4 dry out height dryingheight The height above the depth datum.

Note. The dry height value is in meters (m).

3.5 lamp high elevationoflight The height of the center of the light source.

Note. China's coastal areas are generally counted from the average spring tide surface. Lamp height values are in meters (m).
