Why no ways?

Many reefs appear as long linear objects. RicoZ (talk) 13:58, 23 April 2015 (UTC)

I agree. I will add it to the page. Chrabros (talk) 06:02, 5 March 2017 (UTC)

Reef areas exposed at low tide?

The "Caveats" section suggests that natural=reef should not be used for "features that rise above the water", suggesting one would need to use natural=shoal for this portion of the reef.

But many coral reefs and rocky reefs have small areas sections that are exposed at low tide, and the common definition for "reef" does not require full submersion at low tide: - "1 A ridge of jagged rock, coral, or sand just above or below the surface of the sea." - "1.1 a line of rocks or sand just above or just below the surface of the sea, often dangerous to ships" --Jeisenbe (talk) 12:35, 3 June 2019 (UTC)

I think that caveat refers to features that are permanently above water and those should indeed not be mapped as reef in my opinion. It was a long time ago that I tried to understand all those tags.. RicoZ (talk) 20:21, 10 June 2019 (UTC)
