Relief Shading Now Available for U.S. Coastal and Inland Waters

Relief Shading Now Available for U.S. Coastal and Inland Waters

High-resolution relief shading for U.S. coastal waters and more than 150 lakes is now available for Navionics customers to enjoy on their mobile devices and compatible GPS chartplotters.

Relief shading combines color and shadow to present an easy-to-interpret, clearer view of bottom structure than contour lines alone. Created from multibeam surveys and other high definition data, the Navionics relief shading feature brings bottom detail to life, from shallow flats to deep offshore canyons, in a vivid, colorful representation that helps boaters gain a better understanding of bottom topography for better fishing and diving experiences.

Apple and Android Mobile Devices

With the latest version* of the Navionics Boating app, relief shading becomes available as an additional overlay. Customers with an active subscription can simply download their area of interest, turn on the new overlay and dive in. *Availability of app updates varies by platform and may be delayed slightly for Android devices.

Chart Cards for GPS Chartplotters

Designed with the most demanding boaters and serious anglers in mind, Platinum+ and HotMaps Platinum charts are already preloaded with satellite overlay and SonarChartTM Shading, 3D View, and panoramic photos to provide the ultimate situational awareness, while also offering Navionics+ marine content, advanced features and daily updates for one year. High-resolution relief shading adds a whole new perspective. And, it can be viewed using adjustable transparency with other Navionics chart layers, such as SonarChart 1’ HD contours, for a richer, more informative display. An active subscription is required to download relief shading from using the Navionics Chart Installer.

Currently, relief shading is available for much of the U.S. inland lakes, the East Coast and the Gulf of Mexico, with more areas soon to come. As coverage areas are released, customers who own the Navionics Boating app, Platinum+ or HotMaps Platinum charts with an active subscription will be able to download it.
