Bonjour Nicolas,

J'ai une carte de Bruxelles avec les arrets de bus de delijn.be

http://dxradio.woelmuis.nl/research/delijn/gemeente/gemeentewww/BRUSSEL-STAD.txt/

les autres villes:
http://dxradio.woelmuis.nl/research/delijn/gemeente/

Regardez le code source, et le format de "textfile.txt"

j'utilise openlayers.org

"il faudrait le copier, ymmv."

Marc
