INDEX The index is an A-Z of symbols and abbreviations and enables the user to quickly look up the symbols and see them in context with others in the same categories.
This app is based on the United Kingdom Hydrographic Office's print publication "Chart 5011 (INT 1) EDITION 2" Admiralty Charts Publication and "Chart No.1 United States of America Nautical Chart Symbols, Abbreviations and Terms".
NOTE: ECDIS symbols used to display Electronic Navigational Chart (ENC) data on Electronic Chart Display and Information Systems (ECDIS) as specified by the IHO are not included on this app.
