OK. > http://en.wikipedia.org/wiki/Four_color_theorem Thanks for link, I was not aware of this theorem. > Do you have a specific implementation in mind? Mine initial requirement was damn simple. I did a mapping party for small city Fazilka, Punjab India, and wanted to show following zone in city they have created for Eco Cab. Fazilka Central (Gaushala Road) Fazilka Fazilka West (Vaan Bazaar) Fazilka North (Main Bus Stand) Fazilka South (Multani Chungi) http://www.lovefazilka.esmartweb.com/ecocab.htm http://en.wikipedia.org/wiki/Fazilka#Rickshaw and then I wish to extent it at country and state level, as we always see paper map in that way. > For example, would you > like to have your local OSM tile server show Indian states in the four > color method?
