This is interesting. But what if the (for example) silvopasture would occupy exactly the same area fo the landuse=forest and the landuse=meadow? Of course we could handle this with a new tag landuse=silvopasture. But for other cases? Would it be good to have to exact different way, one with each tag? or better one with the 2 values separated with ; ? Y guess the second solution would be better. But I can't imagine a real case now. For example, the forested military would be probably landuse=military, as it is the main use of the land. The residential area in forest would be just a landuse=residential. Industrial areas in military would again be landuse=military in my opinion, unless the industrial area inside is just let by the military body as a lease for an enterprise to use that piece of land. Same for railways inside military base.

In general, like Florian, I hesitate to have two intersecting areas with the same key (and different values), but Joseph Eisenberg answer makes sense too...

Cheers,

Rafael.

        Hi, all:

        Let's say we have a natural=scrub for example. Inside it (a
        part of it)
        becomes seasonally wet, for example during the rainy (wet)
        season. How would
        you better map this? Some possible approaches:

        1. Having the area of all the scrub as natural=scrub, and the
        area that
        becomes wet in its interior as natural=wetland + seasonal=yes (or
        seasonal=wet_season)

        2. Having a natural=scrub for the whole area, and for the
        wetland area
        temporary:natural=wetland @ (May-Oct) or
        temporary:natural=wetland @
        (wet_season)

        3. Using a relation, with the tag natural=scrub, and the inner
        way with the
        tags natural=scrub + temporary:natural=wetland @ (...)


    For me overlapping natural or landuses are broken. An area can either
    be a natural=wood or a landuse=farmland. You cant include the same
    area in two types of usages or naturals.

You can.
You can have silvopasture ( https://en.wikipedia.org/wiki/Silvopasture )
https://en.wikipedia.org/wiki/File:Silvopasture.jpg

You can have forested military base with wetland (real case).

You can probably find military base (landuse=military) with landuse=farmland.

There are residential areas in forests, there are industrial zones in military bases,
there are railway areas in military bases.

etc etc

You will have overlapping areas or stuff like
landuse=military_industrial_area_under_tree_cover_with_intermittent_wetland
