International HO Charts

Norwegian Charts

The hardcopy maritime chart series comprises standard navigational charts for the coast of Norway, the coast of Svalbard, maritime zones and harbours.

The charts are regularly updated and printed after the initial issue. The time period between each printing will vary depending on the number and type of corrections, sales, etc.

Available Chart Types:

Main charts
Harbour charts
Coastal charts
General charts
Fisheries charts

It is the responsibility of the users to update the maritime charts after the date of the last "Notices to Mariners" that the charts were updated with. In addition to data obtained through surveys carried out by the Norwegian Hydrographic Service itself, information on changes to infrastructure along the coast is also collected from various public bodies. This includes cable data, lights and navaids, bridges, etc. Changes of significant navigational importance are published consecutively in the publication "Notices to Mariners".

US Charts

US charts are produced by the Office of Coast Survey, part of the National Oceanic and Atmospheric Administration (NOAA).

NOAA produces and maintains a suite of nautical charts that cover the coastal waters of the U.S. and its territories.

The traditional paper chart is one of NOAA's signature products. The comprehensive suite of traditional paper charts can be used to navigate the Great Lakes and the coastal waters of the U.S. and its territories. (Traditional charts meet U.S. Coast Guard carriage requirements in U.S. waters.)

When a new chart edition is created, it includes the latest nautical information available to NOAA up until the time of printing. New editions are published when one or more changes of navigational importance render the prior printing obsolete. During a typical year, NOAA may create 200 to 300 new chart editions. The edition number and date (month and year of printing) are found in the lower left corner of the chart. The dates of the latest Notice to Mariners and Local Notice to Mariners corrections applied to the chart are also listed.

The date of a chart is of vital importance to the navigator. When charted information becomes obsolete, further use of the chart for navigation may be dangerous. Natural and artificial changes, many of them critical, are occurring constantly. It is important that navigators obtain the latest edition of a chart, and correct their copies at regular intervals with changes published in the Notices to Mariners.

Canadian Charts

Canadian Hydrographic Service (CHS) produces and publishes almost 1,000 nautical charts covering Canadian waters. Nautical charts show hazards, aids to navigation, features along the shoreline and the seafloor, as well as man-made and natural features of the area.

Canadian charts cover waters used primarily by commercial navigation. Paper charts are hand-amended up to the date of distribution by CHS.

Australian and New Zealand Charts

The United Kingdom Hydrographic Office (UKHO) produce paper charts covering both Australian & New Zealand waters. Admiralty Notices to Mariners, weekly editions, contain information which enables the mariner to keep AUS & NZ charts published by UKHO up-to-date for the latest reports received.

We can also supply charts produced by The Australian Hydrographic Service and Land Information New Zealand (LINZ).

Russian Charts

Nautical charts published by Head Department of Navigation and Oceanography of Ministry of Defence of the Russian Federation (HDNO MD RF) are official documents containing data on navigation, hydrographic, geodetic and hydrometeorologic elements of the situation in areas of oceans and seas and adjacent territories, and in aggregate are intended for navigational safety at sea.

The Russian collection contains 6800 nautical navigation charts, and over 1500 of them are bilingual (Russian and English).
