[mkgmap-dev] multipolygon relation, water

Thu Dec 1 21:10:49 GMT 2022

Hi Brad,

your additional rule is not a good idea, it adds a polygon feature to unclosed lines.
I loaded the relation into JOSM and it complains "Multipolygon outer way shares segment with other ring"
so the relation is invalid and mkgmap probably doesn't render it.
The problem is between these nodes:
https://www.openstreetmap.org/node/8977585639
https://www.openstreetmap.org/node/8977553197

I think this way https://www.openstreetmap.org/way/970139137
should not be a member of the relation.

Gerd

Betreff: [mkgmap-dev] multipolygon relation, water

This water relation doesn't show up on my map.

https://www.openstreetmap.org/relation/370015

I added this to my relations file

type=multipolygon & natural=water
    {
        apply {
        set natural=water;
        set name='${name}';
        }
     }

But still doesn't work.

I have a bunch of natural=water lines in my polygons file for various
sizes & other natural=water ways work just fine.
Any help appreciated.

thx
Brad
