More cyclemap stuff

As usual, when the frequency of posts declines here, that just means there’s more interesting things going on in the real world! I’ve also been trying to avoid writing yet another OSM post, but hey-ho, here’s an update on the cycle map.

Lots more areas are now rendered since I blogged a month ago. Lyon, Vienna, Toronto, Vancouver, Antwerp, Almere, Neuss, Frankfurt, Furth, Karlsruhe, Berlin, Leuven, Bonn and Sydney have all been added along with overviews of some other countries. If there’s somewhere else that you reckon could do with some more zoom levels, just leave a comment or send me an email.

Shelters are now rendered as can be seen in the forests near Bonn, and bike parking has been changed so that small capacity cycle stands show up as blue dots and only larger capacity bike parking areas show quite so predominantly! Previously, it could get quite cluttered as you can see when Tom Chance mapped the cycle parking around the parliament buildings in London. The changes were only partially implemented (or more accurately, I messed up some of the mapnik rules :-) ) so you’ll need to wait a couple of days to see them working properly.

Also fixed was a UTF8 bug in the relations-handling code that meant that some recently-added routes weren’t showing up properly at low zoom levels. We’ve also moved all the contours to the postgis database and stopped pre-rendering them – it turns out the IO hit of loading the transparent contour tiles from disk is greater than just re-rendering them for high zoom levels, and since most of the tiles are high zoom, that’s where the time matters most.
