Bilingual (Chinese and
English) paper nautical charts are produced in accordance with the
specifications of the International Hydrographic Organization (IHO).
The positions on the chart are referred to the WGS84 Datum. The
depths are in metres and reduced to the Chart Datum, which is approximately
the Lowest Astronomical Tide. The buoyage system in Hong Kong follows
the IALA Maritime Buoyage System (Region A), i.e. Red to Port, Green
to Starboard.
The nautical charts are in
five different scales according to their coverage (see
chart index) and usage. The five series are as follows:
