Hi Dave,
you can check the role in the apply rule, something like
(type=boundary | type=multipolygon) & boundary=protected_area & name=*
{ apply role=inner
{
set tmp:role_inner=yes
}
}

display?
Regarding my last post: The rule you gave me works but, as I said, it renders
any boundary that has a name, including in my case, a township administrative
boundary. However, it also renders both inner and outer ways. I'm going to give
up on that for now, unless anyone can think of a way to convince mkgmap to
render inners separately from outers. It's not a big deal. I can easily live
with what I have.
The non-rendering islands issue was my own fault. I forgot to assign role=inner
to the islands in a multipolygon relation they are also a part of. The boundary
rendered fine but there was no "land" showing. (The islands are all outers in
the Kodiak National Wildlife Refuge relation.) Anyway, all is well now.
Thanks,
Dave

That does work but it makes all ways that are named boundary relations ( with
mkgmap:boundary_name =*) render with the same style. I can live with that but
I'm still wondering if there is a way to force it to only operate on inners and
only on ways of type boundary=protected_area ? Can I set in "relations" and
test in "lines" for a new mkgmap:boundary_name, for example, boundary1_name?
Another interesting problem I just noticed is that simple islands (not
multipolygons) whose coastlines are also boundaries do not display as islands,
only as members of the refuge they are a part of. The coastlines fail to
display whether or not the above code is active or commented out so it must be
a separate issue. Take a look at Village Islands inside the Kodiak National
Wildlife Refuge. These display as continuous boundaries with my style
[0x10e12], but there is no "land" inside the boundaries, only sea. So, these
objects are tagged as place=islet, natural=coastline, but they are also outers
in the Kodiak National Wildlife Refuge.

Hi Dave,
there is code in mkgmap to treat multipolygon relations. See mkgmap:mp_created
and mkgmap:stylefilter in http://www.mkgmap.org.uk/doc/pdf/style-manual.pdf
The multipolygon code produces those extra ways only for the outer rings.
If you just want to render the outlines you may use something like
mkgmap:boundary_name=* 0x10e12 resolution 19 continue]
at the top of the lines file.

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.

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
