Not sure if people from those areas feel the same about getting places with latin script in their script. Of course that requires some additional computing power. Would it be an option to put captions (up to a certain extent) on a different layer? Maarten ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

It would be a nice addition if tiles were rendered in local script and latin and shown like that based on preference or viewer location. I would like to see the bilingual style used in the main rendering. That uses name:en when available. As I was asked: The name is created using different views. Code is available for download: http://downloads.osm-tools.org/bilingual/ It needs a patch in mapnik. Either get the patch from trac or wait until it's officially delivered. http://trac.mapnik.org/ticket/584 You could set up multiple fallback languages and redirect the visitor based on the language settings reported by the browser. Even things like use name:de if available, else use name:en is possible. Would it be an option to put captions (up to a certain extent) on a different layer? Some people tried this on Toolserver. It's complicated because different languages take up different space on the map. So the placement of icons is not trivial. I have the feeling that currently it's easier to simply render the language that's of interest. Stephan ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

I did the multilingual overlays on the Toolserver. My first approach was to kick out all Symbolizers from the OSM Style that were no TextSymbolizers. This resulted in Text on the overlays overlapping POI-Icons. The second approach, that's the one that is currently online, renders all TextSymbolizer and all PointSymbolizer but with the PointSymbolizer set to opacity=0. Ævar had a great Idea for a third approach: Only objects that actually have a translation need to be in the language overlay -- all other objects like most streets can go into the base layer. That way the language overlay would become nearly empty on higher zoom levels. To do this, you need a fast way to find objects with translations. To be able to do this I comitted a patch to osm2pgsql that allows you to create hstore-columns for subtags, eg. a column name: that is null if no name:xx-tag is available and that contains a hstore with the translations otherwise. You can then create a conditional index like CREATE INDEX bla ON points (osm_id) WHERE NOT name: IS NULL; to have a fast lookup for translated items. I did a planet import with this column on the Toolserver and developed a style for it but never got around to complete this work. If you or some other wants to talk about this technical point, please come over to osm-dev. Peter ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
[OSM-talk] Bilingual rendering for Greece
Hi, while working on some special purpose map rendering I was told that it would also be interesting for Greece. So here I have a bilingual map rendering for Greece: http://greece.osm-tools.org/ Please let me know if you consider this useful. Currently the map data of *this* map is not updated. In case there is enough interest I can enable it. Would reports of missing names help in making the map bilingual? I created some for Thailand, can do similar for Greece: reports.osm-tools.org Stephan ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
