Overlays work on any map layer and provide a wealth of additional information to help you plan your next adventure. To help you understand what the various colors represent, here is a handy key:
We use a smooth gradient slope shading color scheme to visually represent slope angles.

Our real-time air quality index is represented via a color-coded heatmap, where green indicates the cleanest air and red indicates the most polluted.
Pollen (Pro Overlay)
Pollen concentrations are represented in a color-coded heatmap where green indicates the lowest concentration of pollen and red indicates the highest concentration.
Light Pollution (Pro Overlay)
Areas displayed in red show the most light polluted areas while green shows the least polluted.
