So I have kept an eye on the Cycle Map view to see what would happen, and I think I may have figured it out. Therefore, I thought I'd let you know.</p> <p>What seems to be happening is that the graphics are slowly (and I mean _very_ slowly) being re-drawn over a number of weeks. If you were to add a cycle path to OSM and then view the Cycle Map view after a week, the cycle path might appear on some zoom levels, but not on others. It doesn't seem to matter how much you refresh and/or clear your browser cache, it doesn't appear.</p> <p>This is in stark contrast to the standard OSM view. On there, if you add a cycle path, then within 5 minutes that path will appear in all zoom levels. You need to force a refresh to get it to appear, but it does appear nonetheless, and at all zoom levels.</p> <p>So, what I've taken from this is that the standard OSM map is generated on-the-fly direct from their database, whereas the Cycle Map view isn't; it's generated offline where the images are being created based on the OSM database and those offline images are then cached, rather than re-created everytime someone wants to look at the view.</p> <p>Note that this could all be entirely wrong. &lt;/disclaimer&gt; </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=7428#post-76812 Tue, 03 Jul 2012 20:04:06 +0000 Kenny 76812@http://citycyclingedinburgh.info/bbpress/ <p>I added a few paths about a week ago, but when I use the Cycle Map view, they still don't show up on that, despite the fact that they appear to be identically set up to other paths that *do* show up on the Cycle Map view. Do you know if the Cycle Map view only gets updated rarely? </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=7428#post-76798 Tue, 03 Jul 2012 13:59:16 +0000 chdot 76798@http://citycyclingedinburgh.info/bbpress/ <p><a href="http://www.cyclestreets.net/getmapping/guide/CycleMappingGuide.pdf" rel="nofollow">http://www.cyclestreets.net/getmapping/guide/CycleMappingGuide.pdf</a> </p>
