Relief Shading

Relief Shading

Easily Interpret Bottom Structure

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 alone.

Identify Topography Quickly​

For coastal and inland boat owners who need to know as much as possible about sea and lakes beds, relief shading offers a better understanding of bottom detail for improved fishing and diving.
We use the best data available from our sources.

In some cases, high-resolution data is mixed with low-resolution data to produce a more complete image. The most convenient way to preview relief shading in your area of interest is on the Navionics Boating app.
