Marine Charts and Maps




Charts Can Enhance Your Web Content

All over the world, companies and organizations integrate Navionics charts to their websites to engage online audiences. Boaters worldwide rely on detailed nautical charts and marine data from Navionics for their on-the-water activities. With the web API, this industry-leading content is available to third-party websites and may include standard nautical charts, HD bathymetry and more.

Simplified Web Integration

An intuitive, easy-to-use Navionics web API provides the toolset for embedding selected cartography and features within websites. To use our web API, you need a developer key. This is a short alphanumeric code that allows your application to be authorized to use Navionics cartography and API features.

How to Connect with Navionics Chart Data

Choose the web API access plan that fits your needs.

Garmin makes it easy to select the Navionics data package and pricing structure that works best for your application. Two business models are offered, with different levels of integration:

  • Standard

    This is a free chart viewer that enables third-party developers to integrate the display of Navionics charts within a window on their website, centered in a desired geographic location. Display of additional features on top of charts is not allowed. The service must be free to end users.

  • Enhanced

    This is a paid chart viewer, with an annual fee based on regional or global content. It enables third-party developers to integrate full-page display of Navionics charts—enriched with their own content such as overlays, points of interest, vessel tracking and other features—for their own commercial purposes.
