SYMBOLS, ABBREVIATIONS, TERMS AND S—57 OBJECTS USED ON SINGAPOREAN NAUTICAL AND ELECTRONIC NAVIGATION CHARTS

This renewed release of the publication is mainly basing on the chart specifications that are regularly issued by the IHO (standing for the International Hydrographic Organization). It contains the required abbreviations, symbols and terms plus S-57 objects commonly used in national and international navigational charts published by the hydrographic department of Singapore MPA.

The abbreviations and symbols that are shown on the electronic navigational display systems using VEC may actually be seriously differing from the ones that have been described in the present volume. The publication starts with the introduction and information on the schematic layout of the charts. Then, the "General" part comes addressing the numbering of the charts, positions/distances and marginal notes, directions etc. Remaining parts of this title are dealing with the topography, hydrography, and navigation aids/services. In fact, the layout of this volume is similar to the one applied in this Admiralty publication.

There is some supplementary info at the end of the book, for example containing the abbreviations of the principal terminology in English language as well as international abbreviations. Note the chart reference and projection info contained in the opening chapter of the book, as well as the planes of reference, depths, heights, bearings and vertical clearance.
