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.<br></span></div><div><span class="gmail-im"><br></span></div><div><span class="gmail-im">Dave<br></span></div>

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

<br>
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?<br>
<br>
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.<br>
<br>
Thanks for taking the time to explain.<br>

Hi Dave,<br>
<br>
in the relations rule you set mkgmap:boundary_name but in the lines rule you don't use that.<br>

Betreff: [mkgmap-dev] How can I force the inners of a boundary relation to display?<br>
<br>
Hi,<br>
<br>
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:<br>
<br>
(type=boundary | type=multipolygon) & boundary=protected_area & name=*<br>
{ apply<br>
{<br>
set mkgmap:boundary_name='$(mkgmap:boundary_name)/${name}' | '${name}';<br>
}<br>
}<br>
<br>
Then in my lines file I included a line style defined as: boundary=nature_reserve | boundary=protected_area [0x10e12 resolution 19].<br>
<br>
This works well but the lines bounding the inner areas of these relations do not render. How can I make them display?<br>
<br>
Many thanks<br>
<br>
Dave<br>
