Map internationalization is all about showing maps with place names written in a particular language.
Existing maps and current work
- Serving worldwide alternate tile layers requires a lot of resources, but there are some providers:
- OpenMapTiles demonstrates multilingual capabilities here: https://openmaptiles.org/languages/
- openstreetmap.de displays names in German where available.
- mapcreator by skobbler.de is able to display names of places and streets in many different lingual combinations (English, German, French, Italian, Spanish, Russian, Turkish).
- Multilingual maps Wikipedia project was project kicked off in 2012 to set up rendering infrastructure for Wikipedia (Demo website: http://mlm.jochentopf.com). Uses tiles hosted on tile.openstreetmap.de:8002. currently offline
- There are some maps for special languages in specific areas:
- Bilingual map of Thailand (and some parts of neighboring countries)
- openstreetmap.in multilingual map of india + diary describing it
- tile.osm.be shows the names in French, Dutch and German for Belgium map
- defunct projects/maps
OpenIrishMap showing the same areawhich doesn't seem to be working.
The Frisian language map was probably the first example of OpenStreetMap Map Internationalization (2008) but seems to be broken now. See User:Lambertus#Frisian language map (Fryske kaart)
For his GSoC project Arindam Ghosh mainly worked on Website Internationalization Ideas 2008, but had some other thoughts on map Internationalization. See Talk:GSoC Applications 2008#I18n of OSM pages and map tiles
Before it shut down, WMF-DE's toolserver.org used to have a tile server with a separate layer for each Wikipedia language edition. The replacement tileserver on the WMF Tools Labs only supports English and German.
