The Slope-Angle Shading layer, available in both the Gaia GPS app and on gaiagps.com, makes slope steepness and subtle changes in terrain easier to visualize. It's a useful tool for plotting off-trail routes, scouting campsites, and planning backcountry ski tours.
The Slope-Angle Shading layer is sourced from CalTopo. It's available to users with a Premium Membership.
Transparent areas of the map are less than 27°. Darker-colored shading indicates steeper slopes. The complete map key for the Slope-Angle Shading Overlay is as follows.

2. Add the Slope-Angle Shading overlay to your map sources menu.
3. Adjust the order and transparency of layers as desired.
4. We recommend using the Slope-Angle Shading layer in conjunction with the Shaded Relief (US) overlay, also available in the Premium Overlays category, for clearer visualization of distinct slopes.
