Render peaks

[westnordost]

(from streetcomplete/StreetComplete#3183)

Peaks are landmarks good for orientation.

Text-only, icon-only or both text and an icon?

[westnordost]

I think Icon + Name is fine

[ENT8R]

What about using different icons for light and dark themes?

Light	Dark

Or maybe use the same icon for both styles, as shown in the second row of the table?

[westnordost]

I think this is a good idea. However, I'd propose a simple black or white triangle (pointing upwards)

At lower zoom levels, i.e. when multiple peaks are within view, could we also render elevation of the peak? Would be the nearest approximation to non-existing contour / elevation lines. At those low zoom levels, there shall be sufficient space: Small objects are not rendered. Peaks are usually frequent in areas with few other large objects (high alpine areas).
