[mkgmap-dev] Multipolygon Role Understanding

Wed Feb 10 22:13:10 GMT 2021

Hi all,

sorry, the style file is OK. I just tried with the (locally) corrected MP (removed the leisure tag) and with that the name "Naturfreibad Sankt Märgen" is shown in the map.
I think the multipolygon code removes all tags from the outer way which also appear in the MP. The remaining tags
name=Naturfreibad Sankt Märgen
opening_hours=Jun-Sep: Mo-Su 09:00-18:00
wheelchair=limited
are ignored by the default style.

The behaviour is intended, but in fact a bit confusing.

Gerd

Hi Jan,

I think the multipolygon describes the landuse, the outer way describes the leisure. It makes no sense to have both tags on the MP.
Reg. the missing "Naturfreibad Sankt Märgen":
The default style doesn't use the name of the leisure, neither for the polygon nor for the POI. Not sure why. I would have expected that inc/name does that.

Hi all,

with my limited multipolygon knowledge I stumbled on missing poi tags here:
https://www.openstreetmap.org/relation/4077717

The multipolygon is tagged more limited than the outer role.
mkgmap renders the mp-tags, but drops the more useful outer tags (name etc.).
This useful it´s rendered on openstreetmap, but I can´t get it with mkgmap.
Tried default style and others, even OsmAnd (in OffRoad.jar) - all fail.

So I wonder how or at all I could style the desired display in mkgmap.
Of course the mp itself might be wrong - don`t know - but then I suspect a lot of them ;-/

Jan
