Which sources provide public-domain maps from around the globe that are reasonably detailed and up to date?

Question

Maps are useful in many contexts, and lots of services provide them in various ways.

While I regularly see things like Google Maps published in articles that are supposedly under open licenses, I have not yet seen a service that provides maps that are

• public domain/CC0
• covering the entire globe
• reasonably detailed (say, no more than 100m per pixel in highest resolution)
• reasonably up to date (say, not older than a year)

I am aware of services that are fulfilling some of the criteria, and some of them are listed in responses to a similar question I had posted earlier, but none that fulfill them all, so I would appreciate pointers.

Are you sure the license(s) used by OpenStreetMap are incompatible with your plans?
