Hi, I put a little work in my access map and created some new styles for quality assurance. I tried to keep it as simple as possible, so the drawing scheme is down to six colours and two line types: http://access.t-i.ch/qa-map.html Each of the different (most important) means of transport has its own layer in which *only* explicit acces-Keys (e.g. bicycle=*) are rendered. The second map uses inheritance according to the following tree: http://wiki.openstreetmap.org/w/images/3/3b/Access_hierarchy_simple.png http://access.t-i.ch/qai-map.html AFAIK it's the first map to draw, what routing algorithms already should rely on. I belive that this map will increase the quality of routing information in OSM and therefore enhance OSM a lot. Unfortunately, the result is 17 different styles, but they should not change much in the future. (Hopefully, they don't change at all!) :) The Styles for the first map are: /home/ti/styles/qa/qa-access.xml /home/ti/styles/qa/qa-foot.xml /home/ti/styles/qa/qa-horse.xml /home/ti/styles/qa/qa-vehicle.xml /home/ti/styles/qa/qa-bicycle.xml /home/ti/styles/qa/qa-motor_vehicle.xml /home/ti/styles/qa/qa-motorcycle.xml /home/ti/styles/qa/qa-motorcar.xml /home/ti/styles/qa/qa-hgv.xml The styles for the second map are: /home/ti/styles/qai/qai-foot.xml /home/ti/styles/qai/qai-horse.xml /home/ti/styles/qai/qai-vehicle.xml /home/ti/styles/qai/qai-bicycle.xml /home/ti/styles/qai/qai-motor_vehicle.xml /home/ti/styles/qai/qai-motorcycle.xml /home/ti/styles/qai/qai-motorcar.xml /home/ti/styles/qai/qai-hgv.xml @Peter: I have deleted the old access.xml and bicycle.xml because they are integrated into this new structure. I don't know yet if there will be other *_combined-styles; for the moment bicycle_combined is unchanged. As soon as the styles are rendered, I will post it on the international list. Thanks again, Thomas
