First, let me say I think the maps that Open Street Map are producing look great! So, here is my question(s).
Based on what I can gather from the wiki, it looks like the US data all started from TIGER data and has been updated from there. And, again based on the wiki, all the rendering styles appear to come from the tags that are used (highway=trunk, railway=rail, etc) based on this page: http://wiki.openstreetmap.org/index.php/Map_Features So, how did the conversion from the TIGER CFCC codes to your tags occur? Is there a master list that has the conversion from one set to another? I have been playing with the Mapnik source code for rendering some maps. I have data in a custom format, so I had to write my own driver. Is there some place I can see the style definitions that are being used on Open Street Map? For example, as you zoom in, a road may appears black. Then as you zoom in, it changes to white with a black background. (Python calls them Style and Rule and c++ calls them feature_type_style and rule_type). Thanks!
