inner sections of a multipolygon
Hi Is there any reason why mkgmap only creates the inner sections of a multipolygon if the tags of the outer polygon get transferred to the relation. ie Once you add a multipolygon relation to say an existing forest and making it outer, any inner sections created don't show up unless : the landuse=forest gets removed from the polygon and added to the relation. The problem seems to me that some/many multipolygons have been created by those not using mkgmap. Just an observation ; perhaps this has been discussed before.

This is how multipolygons should be tagged in OSM - forest tags should go to relation, not to outer polygon. Outer polygon is a different geometry compared to multipolygon (polygon with "holes"). For example, lets say you have a park which is mostly trees, but in the middle you have a meadow/grass. You would then have 3 objects: 1. outer polygon which would be tagged as "park" (because park contains both forest as well as meadow) 2. inner polygon which would be tagged as "meadow" 3. relation which is tagged as forest, because forest is everything inside outer polygon except inner meadow polygon. Note different geometries for park and forest. Only relation represents a geometry with a "hole". P.S. JOSM validator reports such errors. I'm not aware of any other validator doing that. -- Tomas
Thanks Thomas for your detailed reply. Would be very useful to have such polygons reported. Nick -- View this message in context: http://gis.19327.n5.nabble.com/inner-sections-of-a-multipolygon-tp5879576p58... Sent from the Mkgmap Development mailing list archive at Nabble.com.
Hi Nick, I think mkgmp can write a lot of messages for wrong multipolygons into the log. You have to activate logging to see them.

Hi Gerd Could you give me a hint as to how I can activate logging? Thanks for your quick answer Nick On 01/08/2016 12:35, Gerd Petermann [via GIS] wrote:
