I don't think the word "location" is very good, but then it wouldn't be the only tag key in use that seems a bit clumsy; I guess tagging is just far enough away from normal use of natural language words that we'll have to put up with that. (I would have chosen the word "level" for this use, and that is not documented as being used, but is it worth trying to change to use it?) I think it makes sense to have one tag that indicates that something is underground, for any type of thing. That means that software (e.g. renderers) can do a simple test for it, and that mappers only need to know one tag for it. And I prefer "location=underground" over "underground=yes" because we could also use "location=overground", and thus still only have to do one check in software to know that something's not at ground level. __John _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
