The document summarizes the OpenStreetMap cycle map, which contains over 47,000 km of mapped cycle routes. It describes how the map is generated from OpenStreetMap data and rendered into image tiles, then hosted on a website. Over 1 million image tiles totaling 23 GB are generated, taking around 5-6 hours. In June 2008, there were nearly 8,000 visitors to the site. Future plans include adding more detailed cycling route information and developing printed map versions.

3. What is the cycle map? How it works Running the Cycle Map The Future?

6. 47,978 km of cycle routes 14,908 km in Germany 11,292 km in UK 6,741 km in Netherlands

17. How it works

18. Download the planet.osm file every Wednesday morning Import into PostGIS database using osm2pgsql Unwind route relations into additional ways (linestrings) Preprepared database of contours from SRTM Custom multithreaded generate_tiles.py using mapnik Grids of .pngs collected into .blk files Rsync to webserver in US PHP script fetches .png out of .blk on demand OpenLayers on website to provide slippy map

26. Running the Cycle Map

27. 1,092,803 png files = 23 Gig 19,717 blk files = 20 Gig 5 hours to download and import 6-7 hours to render about a day to rsync the results

28. 7,961 visitors in June 2008 Most popular tiles: ~ 14,000 hits 1,567 Garmin downloads ... uses a lot of bandwidth

30. The Future?

31. Bus lanes, cycle lanes, opposite lanes shared / segregated / cycle only routes more mountain biking routes and features solving the “tube map” problem junction annotations linear route maps – and paper maps! Bringing more cycle features to the Garmins Hill shading and colouring
