As opposed to "*copier*" which is what we would do if we imported PICC's vector data, "*consulter*" is accessing the raster scan images of their Web servers by any means. "Aucune contrainte d'accès pour la consultation" means that we can do anything with those images, including what I prompted the SPW to write in a OSM tailored document when I recalled what we are doing: "décalquer", "trace", "overtrekken?", something that we learn to do at the kindergarten together with "picoter": put a sheet of paper on top of another and draw what is underneath. > I'm not really sure about this, but I think it could work if the > copyright owner creates some official documentation explaining that > tracing on top of their imagery is not considered copying.

You can ask them to change their site, but I fear that you're getting a huge problem on your hands because there seems to be no Web site in the world that speaks of "décalquer". SPW seems to be the first one to speak correctly, and you would have to ask to do the same to all the world sites too !!! I think that if 99,999% of the users will only figure printing the map or so, the SPW might prefer to not embarrass those users by speaking of tracing and having to answer what it means. They may prefer to issue an OSM tailored version. > > I made an overpass turbo script showing OSM with the Michelin's colors. > > I won't show it because the vigilantes would accuse me to copy > Michelin's colors. > > While doing so, I noticed that the main axis Ans-Amercœur wasn't > fully Michelin's colors. > > So, this could produce suboptimal routes. > > This is because a few N3 streets are tagged highway=secondary > instead of =primary. > > I certainly did not correct that because the vigilantes would say > that it is copying Michelin. > > I'm still of the opinion that we cannot use Michelin to validate our > own map.

For one thing, speaking of colors was a joke but it seems that it unwillingly proved how picky copyright matters can be. First, if anything in copyrights is precise, it seems necessary to clarify what you mean by "validate our map". Second, please let Michelin themselves decide what they allow. My impression from their reply is that they just don't mind. And, if you find it necessary, please add this note to those secondary streets: It is forbidden to change these National roads to primary because someone once notices that they are so on a Michelin map.
Happy mapping, Cordialement, Amitiés, André.
