Jin, I've just imported osm for japan to help get set up for producing products for the quake response.
I've noticing the really large relations that Lennard called out as the problem. I think he was spot on about this being the problem. I have also connected with Artem who appears to have greatly improved Mapnik's ability to handle polygons of this size and complexity. So, I have documented Artem's fix at this ticket: http://trac.mapnik.org/ticket/728 What this means is that Mapnik 2.0 (current trunk) may be *much* more suited for rendering Japan OSM data. To upgrade to Mapnik trunk see this page: http://trac.mapnik.org/wiki/Mapnik2 To get your current osm.xml working with Mapnik2 you will need to upgrade it like: $ upgrade_map_xml.py osm.xml osm2.xml And then use the osm2.xml. Get in touch if you have any questions or need help. I apologize that I did not see this connection sooner. Dane On Feb 24, 2011, at 10:42 PM, Jin Kang wrote: > Sorry everyone!
