Hong Kong Charts (HK)
Availability: By Request
In the context of navigational safety, the Hong Kong Hydrographic Office (HKHO) has taken on a role primarily as provider of nautical information for port users. To achieve this, the HKHO carries out hydrographic surveys continually to gather relevant data which include water depths and seabed nature. Together with other navigational information, up-to-date nautical charts and publications are produced for port users.
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 below) and usage
