World nautical maps : a new layer from NGA catalogue

>>> geolocalization with the Marine GeoGarage <<<

NGA charts are offered for viewing as an additional service for all the countries which don't directly produce nautical charts.

As charts produced by NGA may contain information from other than United States Government sources, copyright restrictions from the country of origin continue to exist in NGA chart content.
(All Rights Reserved).
"The NGA charts are based on "source" data provided by foreign hydrographic offices and therefore these data are subject to foreign copyright as is shown within the "Source Diagrams" on each of the NGA nautical charts."

Some NGA charts use old survey materials and are not regularly updated 
(NOT corrected for Notice to Mariners).
So use these charts as a ready reference or in situational awareness or as a planning tool.

All NGA charts and maps are for reference purpose only.

These charts are for countries where no locally produced RNCs exist.
NGA charts are quite a bit out of date (15 - 30 years) - not even updated for their own NOTAMs.
But they can be used for a general area coverage and passage planning or "armchair sailing" at home.

For more information about NGA products, visit the NGA website.
To report any NGA chart discrepancies, please send an email to

Note : some NGA charts for North America, Western Africa, Mediterranean, Black Sea, Eastern Asia, South Eastern Russia, Philippines remain also available for viewing on the NOAA website.
