Shields are supposed to start rendering at zoom 10, but they're not. This is a bug. What the rendering should be is: motorway shields at zoom 10, plus trunk and primary at zoom 11, plus secondary at zoom 12, plus everything else at zoom 13. I'm working on just doing Interstates (and the Trans-Canada Highway, pending some discussion about how to properly tag it on talk-ca@) starting at zoom 7, but that's not in the tiled rendering yet. > Yes, 12, 13 and up to 14 work, but 15 and above just display pink tiles. It depends on where you are looking. If you're getting a lot of pink tiles, that's probably because they haven't been rendered yet and the server is taking too long to render them, so your requests are timing out. There should be an error tile suggesting that you wait a bit and try back later, but that doesn't always load properly. Everything up to zoom 12 is prerendered. Zooms 13 and 14 can be slow to render, but 15 and up normally go quickly except in dense urban areas. > Most specific shields in California look "good and familiar," as you > make correct distinctions between Interstates and state routes. > However, "county routes" (designated by a "regional letter" and a > number, such as "S 21") are not rendered with proper shields at all. > This is a critical component for many areas. I'm deliberately leaving county routes for a second phase and focusing on state routes for the moment. (New Jersey is an exception, but it was an experiment and I don't actually believe we're using the proper shields for all of its counties.) > And oddly, in the San Diego area, "CA 209" and "CA 75" (Point Loma > and Coronado, respectively) don't render with your newer shields, > but the old style Mapnik shields. It looks like there aren't route relations for those routes yet, so the rendering falls back to the old shield style for them. > Also, there are some toll ways in Orange County (California, e.g. CA > 73, CA 241) which don't render specifically as toll, but as there is > no distinct shield in California to distinguish toll roads, I'm not > sure this is a defect in your algorithm or renderings -- the regular > state route shield is displayed, apparently correctly. Do toll roads get any difference in signage, like a banner above or below the shield? If so, then we just need to make images that match and get routes that identify them. (Right now that would probably be with a network of US:CA:Toll, but see NE2's and my emails about Florida toll roads.) > I also see absolutely no business routes where I know them to exist. > I'm still searching for some in your rendering, but haven't found > any (yet). They might not show up. Based on previous discussions on this list, we've chosen to look for the business designation (as well as others) in the network tag on the route relation. A lot of relations have the route modifier in the ref tag, though (so they might be network=US:US, ref=5 Business instead of network=US:US:Business, ref=5), so they don't get rendered at the moment. (And on top of that, there are slightly different signs for spur and loop business Interstates, so I ended up looking for networks like US:I:Business:Loop and US:I:Downtown:Spur even though no one's actually doing that yet.) There are some business routes that our rendering understands here: http://elrond.aperiodic.net/shields/?zoom=12&lat=38.36793&lon=-75.59339&layers=B0 -- ...computer contrarian of the first order... / http://aperiodic.net/phil/ PGP: 026A27F2 print: D200 5BDB FC4B B24A 9248 9F7A 4322 2D22 026A 27F2 --- -- Plumber mistook routing panel for decorative wall fixture. -- BOFH excuse #55 ---- --- -- _______________________________________________ Talk-us mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk-us
