Is it possible for anyone to view that mapping view through Cycle Streets?No due to reasons of poor performance, hence why I'm asking is someoneelse would be interested in implementing something similar with far better performance and global coverage. The original authors would be really happy to see it implemented elsewhere, as it would bring great benefits to the OSM data.As a quick hack I have generated such a map for the UK. http://www.gedanken.org.uk/mapping/osm-junctions/junctions.html The junction data comes from Routino[1] and as such not all highway junctions are included (only highways that are routable). The rendering is performed client-side so is rather slow (probably my Javascript isn't optimum). The server will only allow downloading a limited amount of data at a time so I recommend you zoom in to the highest or penultimate zoom level.
Nice start.I'd like to be able to zoom in more, particularly in central London. I've also found that clicking "Get Junctions" often gets an area, where only a little bit is visible at the highest zoom, and you have to pan and re-request to get for the current area. I'd also like a permalink, and a link to the osm site for easy editing.
