Yes, that's confusing to me. I included those snippets to illustrate what I am currently using — maybe you can explain to me stepwise how those boundaries get rendered?

Is there code inside mkgmap that interprets such directives and applies tags to the outer ways of relations? If there is then I assume the same can be done for those inners. And you would be the one who can best answer that question.

Thanks for taking the time to explain.

Hi Dave,

in the relations rule you set mkgmap:boundary_name but in the lines rule you don't use that.

Betreff: [mkgmap-dev] How can I force the inners of a boundary relation to display?

Hi,

I've been adding large Alaskan National Wildlife Refuges to OSM. The boundaries weren't displaying so I added a directive in my relations file modeled after the administrative boundary code in the default style that adds a name to protected areas like so:

(type=boundary | type=multipolygon) & boundary=protected_area & name=*
{ apply
{
set mkgmap:boundary_name='$(mkgmap:boundary_name)/${name}' | '${name}';
}
}

Then in my lines file I included a line style defined as: boundary=nature_reserve | boundary=protected_area [0x10e12 resolution 19].

This works well but the lines bounding the inner areas of these relations do not render. How can I make them display?

Many thanks

Dave
