Hi!

A very good hint. The understanding of all discussions on the matter
is that the current OSM licence does not allow mixing with CIAT data
nor with ASTER data. So you cannot publish those maps.
Could you elaborate on this? I would understand that e.g. the license of
the ASTER data forbids publishing of derived work (although I haven't
checked this). But is there really a point in the OSM license which
forbids creating derived works (maps) which as an "add-on" contain
features created from proprietary data sources?
Yes. To put it very simple: The share-alike cause of the OSM licence
requires you to make everything available under the OSM licence again.
If you combine OSM with other data which has _any_ form of restrictions
or any different interpretation of freeness, you are breaking one of the
licences.
A common workaround is to add the combined data in an extra layer and
claim this makes a collective work. This is not legally sound, but has
never been challenged.
I am putting my hope in the new licence which would allow you to create
such a combined work.
