Today 397 charts (737 including sub-charts) are displayed in the France SHOM GeoGarage layer.
Note : The SHOM produces official nautical charts to aid safe navigation in France waters and certain areas of Africa, Antarctica, West Indies and the South-West Pacific.
Using charts safely involves keeping them up-to-date using Notices to Mariners
Mariners are requested to advise the French Hydrographic Authority at SHOM of the discovery of new or suspected dangers to navigation, or shortcomings in charts or publications
