golf=bunker should use surface

[DaveF63]

Given it's been agreed in #203 that other golf features use the surface tag to indicate their, err... surface, it appears illogical to auto add natural=sand to golf=bunker.

natural=* is a primary tag, designed to be used in isolation, not a supplementary, sub/adjective tag.

Oh, and not all bunkers are sand.

Earlier this year, the wiki still recommended natural=sand (or surface=sand), but I agree that surface would do a better job at it.

not all bunkers are sand.

Oh, really? What other types of bunkers exist? FWIW, at least the USGA considers bunkers to be a term specific for sandy obstacles:

Bunkers […] are specially prepared areas intended to test the player’s ability to play a ball from the sand.

natural=* is a primary tag, designed to be used in isolation, not a supplementary, sub/adjective tag.

in some cases multiple primary tags may apply (though in this case using surface is not making things worse)

BTW, #409 appears to request exact opposite

Admittedly, they're much rarer, but they do exist, even in the US.

Hm… these things should probably be mapped as golf=rough instead of golf=bunker, as they are not actually bunkers:

Important note: Grass bunkers are not, technically, bunkers at all under the Rules of Golf. […] A grass bunker, therefore, is treated as just any other grassed area of a golf course, any other patch of rough.

Disagree.
Primary: "First in a group or series.", "placed ahead of others."

Do you have any OSM examples?

[matkoniecz]

Do you have any OSM examples?

amenity = drinking_water
man_made = water_tap

amenity = place_of_worship
man_made = cross

amenity = place_of_worship
building = chapel

amenity = shelter
building = yes

amenity = drinking_water
man_made = drinking_fountain

[DaveF63]

?!?

I'll discuss these on another forum as this one is inappropriate.

amenity = drinking_water
man_made = water_tap

Feel free to ping me here or via mail if that is not tagging mailing list or OSM wiki with ping template being used.

And this combination is perfectly fine.

What you're actually quoting is The R&A. (I believe they're on the telly at the moment). Their concern is with the likes of competition courses.

Around the world there are hundreds of smaller courses, municipal run pitch 'n' putt etc which can have grass covered craters to reduce maintenance costs.

To check, are there any other tags prescribing natural-sand or is this swap purely golf=bunker?
