Hello,<br><br>I am trying to update my shp-to-osm tool [0] to chop up ways with >2000 nodes into smaller ones. Part of this task involves advanced multipolygon support [1]. It seems as though I'm doing the right thing: ways longer than 2000 nodes get split and the first node of way A and last node of way B are the same. They're all made part of a multipolygon relation with role=outer.<br>
<br>However, when I try to open this file in JOSM and see what happens with the non-wireframe renderer, half the screen turns red when I select the way.<br><br>What is the "correct" way to tag and build these features? Am I missing a step somewhere?<br>
<br>Thanks!<br><br>[0] <a href="http://redmine.yellowbkpk.com/projects/show/geo">http://redmine.yellowbkpk.com/projects/show/geo</a><br>[1] <a href="http://wiki.openstreetmap.org/wiki/Talk:Relation:multipolygon#Advanced_multipolygons">http://wiki.openstreetmap.org/wiki/Talk:Relation:multipolygon#Advanced_multipolygons</a><br>
