Where do you get the information you use in Navionics Charts?
It may vary by Navionics product as well as by continent, country and/or area, but most commonly Navionics sources its data from official government hydrographic offices such as British Admiralty and SHOM to name just a few. Navionics also conducts its own on-the-water surveys when existing information is not available, is out-of-date, or is not of good quality.

What type of detail do Navionics Charts show?
Navionics Charts show depth contours, spot soundings, navigational aids, boat ramps, marinas, obstruction information such as reefs, wrecks, and submergent and emergent vegetation.

If Navionics does not currently have coverage for my lake or coastal area, how can I obtain this coverage?
To request new coverage for coastal areas or lakes and rivers, please send an email to info@navionics.it. Areas with the greatest number of requests have priority in the development department.

What datum setting does Navionics use for their Charts?
