Making the maps you can download from this site and keeping them updated takes a lot of time and dedication. I also spend a great effort completing and fixing OpenSetreetMap data, to make the map better each day. Downloads are free, but I think it's fair to give something back, so I ask you to donate now. If you want to give your support to help maintaining and improving this service, you can donate any monetary amount. I will thank you even if it is small.
