Область применения
This standard specifies the symbols, abbreviations, and terms used on Chinese nautical charts, along with the methods and requirements for their application. It is applicable to the surveying, compilation, and publication of nautical charts at various scales. It serves as the fundamental basis for identifying and using Chinese maritime charts and can be referenced for drafting specialized thematic charts.
Технические требования
The standard defines the general rules for symbol classification, sizing, positioning, and orientation on nautical charts. It specifies the use of scale-dependent symbols (true to scale, semi-scale, and non-scale) and establishes precise rules for symbol placement relative to geographical features. Cartographers must strictly adhere to these positioning rules to ensure navigational accuracy. It details the representation of natural geographic features, artificial structures, and land navigation landmarks. This includes specific symbol designs for coastlines, relief, water features, settlements, roads, and prominent landmarks like wind turbines and helicopter airports. The standard also covers maritime elements such as ports, tidal and current data, depths, and seabed materials. A significant portion of the standard is dedicated to navigational aids and maritime facilities. It provides comprehensive symbol sets for lights, buoys, beacons, fog signals, and radar/radio positioning systems. These symbols are critical for safe maritime navigation and must be rendered accurately according to the specified colors and shapes. The standard also incorporates modern elements like AIS virtual aids and differential GNSS stations. The document includes normative appendices for chart numbering, title styling, and border decoration. It also provides informative appendices such as a Chinese-English geographical generic terms comparison table and common abbreviation indexes, ensuring consistency across international and domestic maritime communications.
Методы испытаний
The standard outlines specific drafting and representation procedures rather than physical testing methods. It specifies color requirements (typically black, yellow, purple, and blue) for chart printing and defines the exact dimensions and line weights for all cartographic symbols. Evaluation of compliance involves verifying that chart elements are positioned, scaled, and annotated according to the detailed symbol libraries and layout configurations provided in the standard's appendices, referencing IHO regulations and IALA maritime buoyage system principles.
