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

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
  }
}

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

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
