Relief Shading - What is it?

i-Boating relief shading is like Google Street View, but for underwater terrain (Sea View). It's a visual representation of what the underwater terrain looks like. If you were to drain the oceans/lakes of all the water, that is the kind of view relief shading attempts to show.

FAQ for Relief Shading

Q1 Can I disable contours with relief shading enabled?

A1 Yes, simply check the box “Disable Depths” on top when relief shading layer is enabled.

Q2 Is Relief Shading like Google Street View for water?

A2. Yes, in a sense. Street view relies primarily on data collected from light sensors. That is not an option for underwater surveys. The i-Boating relief shading is created from bathymetry data from hi-resolution sonar surveys.
