Hi Finally, I found some time to set up a base layer in greyscale. I did this by automatically converting the original mapnik style and all icons. http://picpaste.com/pics/mapbw.1287869339.png There are some caveats: the style is named osm.xml and refers to ./inc and ./style which contain different (i.e. b&w files) than the original mapnik. I don't know if this is incompatible to the way all the layers are bound into Tirex, please tell me so. The style can be found here (on willow): /home/kayd/workspace/parking/mapnik/bw-mapnik I'd very much like to see it included as a base layer here: http://toolserver.org/~osm/styles/ I'd like to hear about your opinion: would you rather like a b&w base layer that's identical to current mapnik, or should it omit most of the icons (shops, etc.)? Or is both needed? Main uses would be IMHO the bicycle overlay (which looks a bit lost with the colorful mapnik base layer) and similar layers. Kind regards, Kay
