Just to let you know that at ITO we are now very close to releasing a set of
specialist renderings which might meet your requirements. These views will
*Power lines, generators, substations etc (lines colour-coded by voltage if
*Road speed limits (colour coded by speed limit if available)
*Railways (colour coded by line type - mainline, subway, tram, light rail,
preserved, abandoned etc)
*Railway track width (1, 2 or multiple is available)
* and more that may be suggested
ITO will manage all the data hosting, scripts and tile rendering. The
service will be available globally and the data will be updated daily.
Initially we will define the scripts to avoid to much rendering work for our
servers. Our intention is to then release the 'scripting' to allow people
to create and publish their own scripts.
More details soon!
