Available Navionics Platinum+ Map Overlays

High-Resolution Relief Shading

For coastal and inland boat owners who need to know as much as possible about depths and bottom structure maps, Relief Shading delivers highly detailed shading that combines color and shadow to provide an easy-to-interpret, clearer view of bottom structure than contour lines.

Satellite Imagery

Offered as a separate overlay that can be displayed over land and water to give you a realistic view of your surroundings — ideal for entering unfamiliar harbors or ports. 

Sonar Imagery

The sonar imagery feature reveals bottom hardness clearly and in vivid color, highlighting both subtle and dramatic transition areas. Available on select lakes.
