How it works

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

Running the Cycle Map

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

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

The Future?

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
