Alberto and you are often using nice maps like this one. They are not very detailed, but I like them. What is your source? Do you get them on-line, or do you scan them?
I know good on-line sources for Switzerland, Austria and France. But for Italy I know only "Geoportale Nazionale", which is on this link:
Do you know any better on-line source for maps? For private, non-commercial use only, of course ;)
sorry, but i can help you about this question, because i obtain the maps i use by scanning the images from my guidebooks or maps, then modifying those (for example changing colours) for adapting to the specific pages. I don't use on-line maps.
Ciao and have a nice evening!
Good effort, because maps really tell a lot.
