[OSM-talk] Bikely OSM?

[80n]

Steve
I've played around with this idea in the past and came up with a working
proof of concept:
http://www.informationfreeway.org/gjs

Click on "From M3 (Junction 3)" or "From Waterloo (Slow Train)" to see the
routes in red (car) / blue (train).

This was done by adding route tags to existing ways in OSM using a private
namespace (clopin).  For example: clopin:route=train or clopin:route=car or
clopin:route=bike.

I then created a very small Osmarender rules file that rendered just the
clopin tags. I fed this into the tiles at home client to generate a transparent
tileset containing only the red / blue routes.  I then saved this tileset on
a local server (it is quite small, most tiles are empty).

Finally, I created an OpenLayers instance that uses the main t at h base layer
with my clopin layer on top as a transparent overlay.

I repeated this for each route I wanted to display, and then used a bit of
javascript to switch on/off each transparent display.

Sadly I have been too short of time recently to finish it off, but once set
up properly it could be pretty quick and easy to generate customer layers
based on a selected set of clopin tags added to existing ways.
