@Christoph, Thanks for the feedback and the references to the previous discussions about this topic. The first reference to an earlier discussion on this list was particularly useful. From your email and that thread, I gather that you are opposed to mapping bays and straits as multipolygons. That

Here in Indonesia it is very common for neighbors to build sign over the main entrance to their neighborhood, with the name of the neighborhood on top and some other info on the two columns supporting the sign. In this example there are two different gateway signs, on the small street to the left

In Turkmenistan I have tagged such signs (though they are official, and for villages/towns) as tourism=information, information=board or information=name depending on how much info it contains.  If there is a better tag, I am all ears. On 11/16/2018 7:44 AM, Paul Johnson wrote: > On Thu, Nov 15, 2

Please look at the examples in Indonesia. They are not sculptures or artwork. And they are erected by the very local government at the neighborhood level.

It appears I've started another long discussion that will resist any attempts to produce a clear answer. I think it's fair to assume that because this is OSM each mapper can decide for him or herself how to map bays and straits. That is, as long as someone with greater power than any of us decodes
