Re: [mkgmap-dev] multipolygon with outer polygon within inner polygons

Hi WanMil,

2nd: the multipolygon code should not remove the boundary tags from the singular ways. Additionally the polygons created by the multipolygon code could be tagged with mkgmap:mp_boundary=yes. This tag could be evaluated in the style definition so the style could differ between the polygons created by the mp code and the lines not touched by mp code.

This sounds sensible to me. The style could have an additional rule that filters out generated lines. I would set the attribute on all MultiPolygon-generated lines, not just on boundaries. (Someone could want to draw coastlines as lines on a separate map layer, for example, and the generated lines would interfere.) Marko
