Why not ask your question on the new OpenStreetMap Community Forum?

What licences are allowed for my own tiles when the database is ODbL now? For example, map1.eu has tiles under CC-BY-NC-ND. Is the NC-ND not against ODbL's copyleft requirements?

Map tiles are a "produced work". You can release them using any license you like.

The viral part of the ODbL only kicks in when you create a "derived work". E.g. when you combine OSM data with another dataset into a new "database".

Try plugging "ODbL produced derived" into your search engine of choice and you will find many lengthy explanations/discussions.

Sorry but the answer is not quite correct, you can release a "produced work" under any licence as long as clause 4.3 of the ODbL is adhered too which essentially boils down to a attribution requirement.
