In addition to the above, ITO will shortly be releasing a number of
additional views of the data together with a way of simply defining
additional views. The rending will be reasonably basic compared to Mapnik,
however the scripting will also be simple. We are going to start with some

Written last night, so some of this goes over ground already covered.
At one stage someone was doing a canal waterway map, but I think those
involved have other time commitments, like maintaining OSM editors and doing
the
default cartography.

Nice power map! Does it take account of the new, more powerful tagging
schema?

It can certainly be done if you're prepared to put the effort in. Bear in
mind that OSM isn't really an end user map
Hi Chris,
I've read through the replies to your post and my take on this is
client side rendering - it's hard to make this as pretty or neat as
bitmap tiles, but for random exploration of the dataset it's
powerfull.

I'll have a look at how it works tonight - It is getting the power source

analysing the tags used in the databse rather than reading documentation -

Richard, have you got (or know of) an example of this which is up and

There's an old old version at http://www.geowiki.com/halcyon/ . I'll
try and put a new version up this weekend.

Henry,
I think you are describing what my examples do - for example the map at
http://maps.webhop.net/topo uses a simple base map and the OpenLayers
javascript program running in the web browser draws the selectable overlays
on top of it - the overlays are PNG images with a transparent background.
Hi Folks,
Using transparent overlays is easy - you do not need to do any real time
processing - just get an image from a server and dispaly it. Going for
something cleverer like vector rendering needs a database to give you the
correct data, then the javascript in the web browser needs to

Many thanks to everyone who's replied. I have a page full of notes from

I think that a static (periodically refreshed) 'binary tile'
architecture where the OSM DB is boiled down into tiles designed for
the single purpose of being rendered quickly is the way to go.
Ideally a map viewer can then call upon both the standard bitmap tiles
and the vector tiles and combine
I've also got an interest in waterways and found it was possible to make
them leap out using OSM Inspector in the Geofabrik Tools website

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
