Admiralty Charts
Over 3,500 Standard Nautical Charts (SNC) are available under the Admiralty brand and cover virtually the entire world in various levels of detail depending on the density of traffic and hazards.
Large-scale charts often cover approaches and entrances to harbours, medium-scale charts cover heavily used coastal areas, and small-scale charts are for navigation in more open areas.
Admiralty standard nautical charts use the Mercator projection so that bearings can be transferred to (or taken from) the charts directly.
