Hi Folks,<div>To reply to the original question, I have had a <b><u>very</u></b> quick go at rendering an overlay showing canal infrastructure over the standard OSM map rendering.</div><div>The higher zoom level tiles are still generating, but most of it is at <a href="http://maps.webhop.net/canals">http://maps.webhop.net/canals</a>.</div>
<div>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!).</div><div>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.</div>
<div><br></div><div>This is a very crude rendering - What it does is:</div><div><ul><li>Extracts all data that is tagged waterway=<something></li><li>Draws blue lines where waterway=canal</li><li>Draws blue dots where waterway=lock_gate or lock=yes</li>
</ul><div>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. </div>
</div><div>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!).</div><div><br></div><div>Regards</div><div><br></div><div><br>

<br>A bit long, but it works. <br>Waterway data has the potential to be some of the most "accurate" in OSM due to the very high quality water line data made available in OS VectorMap_Data.<br><font color="#888888"><br>

I'm interested in the GB waterways and it seems there's quite a bit of work done but it's totally invisible. Is anyone working on a layer like the cycle map, which leaps out from the overlays as the only minority interest yet developed?<br>
<br>
It's not the only layer I'd like to see. What about walking paths, railways, contours, points of interest, postcode areas, administrative boundaries, constituencies, bus routes, etc., etc.<br>
<br>
Shouldn't maps allow you to concentrate on whatever you're interested in? Can someone please explain to me how or if this can be done with openstreetmap?<br>
