How We Work

New Data Sourcing

We integrate all sorts of new data from official hydrographic services and private entities. Our aim is to generate a comprehensive product that goes well beyond official HO charts. This is why we constantly scout new sources and carefully select the content that ends up in our final product. We choose different sources for different areas in order to maintain our high standards and continue serving our customers with the best detail possible.

Integration and Processing

Only Navionics delivers updates in such an incredibly timely way. On average, we integrate new data within 15 to 30 days from publication by the original source. New data include, but are not limited to:

- Notices to Mariners, over 20.205 since January 2021!
- ENC data S57
- surveys
- and more

SonarChart™, our 1' HD bathymetry layer, is constantly enhanced by millions of sonar logs from boaters like you. These new contributions, coming from all over the world, are integrated with existing data to reflect the ever-changing conditions of sea, lake, and river bottoms at a very local level.

SonarChart Shading, Relief Shading and Sonar Imagery chart overlays are updated periodically as new or better source data is acquired and integrated, allowing us to deliver expanded coverage and improved quality.

Navionics charts include more than 40,000 lakes worldwide. But that’s not all of them. We constantly source new data, so no matter where you are, you can boat and fish at a lake nearby.

The forces of nature, as well as construction projects like dams, dredging and marina development, affect the shape of coastal, lake, and river shorelines. Our experienced cartography teams meticulously review and redraw these features as they change over time.

Build it and they will come. Fish seek out particular types of habitats where they prefer to nest. In many lakes and coastal waters, angling clubs and fisheries organizations will sink structures to attract fish and encourage a healthy fishery.

Nothing ruins your boating day like hitting a rock. In addition to our own research, we encourage boaters to share the locations of underwater and exposed rocks. These potential hazards are displayed clearly within our products, making boating safer for everyone.
