ODbL (which is the license for the data) doesn't require any particular license for maps produced from ODbL data. (And in the U.S. data isn't copyrightable anyway.) There is a copyright on the style and presentation of the tiles which is separate from any copyright on the data. This copyright belongs to whoever created the styles for the tiles (or their employer). Unless whoever that is explicitly puts it under a license, the style of the tiles is fully copyrighted (in the U.S. at least).

I feel like there's an argument to be made that the images are a derived work from the data itself, so it may be best to just stick with OSM's license rather than run into any possible issues. (Also, of course, I am biased and prefer copyleft licenses since they support free information.)

And in case that isn't decided, I would suggest CC0 so that we don't have to link to a big explanation from each tile rendering :)

What is the license for the map tiles, i.e. the cartography rather than the data? Open Street Maps uses CC-BY-SA, although they don't really
make
it clear who is supposed to be attributed. It looks like our tiles are different though.

The Discovery Department has launched an experimental tile and static
maps
service available at https://maps.wikimedia.org.
Using this service you can browse and embed map tiles into your own
tools
using OpenStreetMap data. Currently, we handle traffic from *.wmflabs
.org
and *.wikivoyage .org (referrer header must be either missing or set
to
these values) but we would like to open it up to Wikipedia traffic if
we
see enough use. Our hope is that this service fits the needs of the numerous maps developers and tool authors who have asked for a WMF
hosted
tile service with an initial focus on WikiVoyage.
We'd love for you to try our new service, experiment writing tools
using
our tiles, and giving us feedback < https://www.mediawiki.org/wiki/Talk:Maps%3E . If you've built a tool using OpenStreetMap-based imagery then using
our
service is a simple drop-in replacement.
Getting started is as easy as https://www.mediawiki.org/wiki/Maps#Getting_Started
How can you help?
- Adapt your labs tool to use this service - for example, use Leaflet
js
library and point it to https://maps.wikimedia.org
- File bugs in Phabricator
https://phabricator.wikimedia.org/tag/discovery-maps-sprint/
- Provide us feedback to help guide future features
https://www.mediawiki.org/wiki/Talk:Maps
- Improve our map style <
https://github.com/kartotherian/osm-bright.tm2
- Improve our data extraction
https://github.com/kartotherian/osm-bright.tm2source
Based on usage and your feedback, the Discovery team https://www.mediawiki.org/wiki/Discovery will decide how to
proceed.
We could add more data sources (both vector and raster), work on additional services such as static maps or geosearch, work on supporting all languages, switch to client-side WebGL rendering, etc. Please help us decide what is most important.
https://www.mediawiki.org/wiki/Maps has more about the project and related Maps work.
== In Depth ==
Tiles are served from https://maps.wikimedia.org, but can only be accessed from any subdomains of *.wmflabs .org and *.wikivoyage.org.
Kartotherian
can produce tiles as images (png), and as raw vector data (PBF Mapbox format or json):
.../{source}/{zoom}/{x}/{y}[@{scale}x].{format}
Additionally, Kartotherian can produce snapshot (static) images of any location, scaling, and zoom level with
.../{source},{zoom},{lat},{lon},{width}x{height}[@{scale}x].{format}.
For example, to get an image centered at 42,-3.14, at zoom level 4,
size
800x600, use https://maps.wikimedia.org/img/osm-intl,4,42,-3.14,800x600.png (copy/paste the link, or else it might not work due to referrer restriction).
Do note that the static feature is highly experimental right now.
We would like to thank WMF Ops (especially Alex Kosiaris, Brandon
Black,
and Jaime Crespo), services team, OSM community and engineers, and the Mapnik and Mapbox teams. The project would not have completed so fast without you.
Thank You
