Hi Folks, To reply to the original question, I have had a *very* quick go at rendering an overlay showing canal infrastructure over the standard OSM map rendering. The higher zoom level tiles are still generating, but most of it is at http://maps.webhop.net/canals. It is running on my home server, which is a nice fast computer, but it is behind a slow domestic broadband connection, so it will seem rather slow to load from the outside world (sorry!). It looks like the tile set is going to be about 1GB, so I can probably find somewhere to host it faster if people are interested in it.
This is a very crude rendering - What it does is: - Extracts all data that is tagged waterway=<something> - Draws blue lines where waterway=canal - Draws blue dots where waterway=lock_gate or lock=yes If anyone is interested in improving this, the 'about' page contains a link to the mapnik xml file (canal1.xml) that I used to render it - please feel free to suggest changes, draw little icons to replace my stylish blue dots etc. If you want to do something with it but are not familiar with mapnik, let me know and I can explain how it works (as far as I know - I am no expert!). Regards Graham.
