Q. What is OceanGrafix’s relationship with NOAA?

A. In June 2000, OceanGrafix was selected as NOAA’s partner in the development of a new generation of nautical charts for U.S. waters. Using digital technology, OceanGrafix is able to continually incorporate NOAA’s latest cartographic changes — and then print these fully up to date charts as they are ordered. The new charts were first introduced in 2002, and OceanGrafix continues to produce them today under an exclusive contract with NOAA.

Q: What is meant by “Notice to Mariners?”

A: Each week the National Geospatial-Intelligence Agency (NGA) issues the Notice to Mariners (NTMs) for ocean-going vessels, providing timely marine safety information for the correction of nautical charts. You can review the Notice to Mariners at http://msi.nga.mil/NGAPortal/MSI.portal. OceanGrafix NOAA charts for U.S. waters include all Notice to Mariner Corrections issued prior to the time of printing.

Q: What is the “Local Notice to Mariners?”

A: The nine district Coast Guard offices issue the Local Notice to Mariners (LNMs) each week, applicable to all vessels. The LNM provides timely marine safety information including the correction of nautical charts, the US Coast Pilot, and the USCG lighthouse list. The list also pertains to aids to navigation, lights, bridges, cables, pipelines, wrecks, obstructions, Federal Waterways, waterway operations and dangers to navigation. LNMs are published at http://www.navcen.uscg.gov/?pageName=lnmMain. OceanGrafix NOAA charts for U.S. waters include all Local Notice to Mariner Corrections issued prior to the time of printing.

Q: What is meant by a chart “Edition?”

A: A new “Edition” brings a NOAA nautical chart up to date for all chartable information available to NOAA, including hydrography, shoreline and marine safety information published in the LNM and NM. Additionally, NOAA makes some minor changes, which make the chart more useful. About 250 new editions are issued per year with the time between new editions ranging from six months to several years. The status of new editions is published at http://nauticalcharts.noaa.gov/mcd/dole.htm. Note that new “editions” are issued by NOAA periodically, but that OceanGrafix on-demand charts for U.S. waters contain every NTM and LNTM as they are downloaded daily by OceanGrafix.
