Mikel is right on - we don't need to wait! : ) https://github.com/OpenHistoricalMap/openstreetmap-carto
You're absolutely correct about the default (tele-tubby) style looking funky for the Seattle data and even more correct about the need for tagging and styling discussions. Right now, there are a bunch of issues of with the Seattle map that highlight OHM issues across the board: - Modern tagging structures may not be relevant in the past - e.g. roads vs. tracks -- I hacked up the core data to get around the rendering issues, but that's not a generally good habit - Bad coastline (not really a style sheet issue, but a problem with the resulting output) -- We need to add a coastline generator process - Dirt roads end up looking like dashed lines, even though they are the main road -- And... should dirt roads have "casings"? - The wooden pier that was the hub of much of Seattle's commercial businesses doesn't show up -- I've started hacking around (very ugly style) with the OSM carto in TileMill to fix this. -- see: http://i.imgur.com/CJWenXP.jpg So... I agree: styling and tagging need to support much more than they do now. Want to start a tagging page for discussions on the wiki? (Or somewhere else appropriate for collaboration?) http://wiki.openstreetmap.org/wiki/OHM Thanks!
