I consume OSM data, adapt it for my needs by adjusting OSM geometries to match CC-BY licensed aerial imagery, and then publish the result publicly.
To comply with the OSM data's ODBL license, my published results contain a notice that it is "based on data (c) OpenStreetMap Contributors under the Open Database License http://www.openstreetmap.org/copyright";. To comply with the CC-BY license, I also add that "In part derived from [name of work], CC BY 3.0 licensed, [link to work]". Is this okay? However "CC BY 2.0, 2.5, and 3.0 are clearly incompatible, thanks to the attribution requirements that can't be met."[1] and "It is ... not clear if the CC 4.0 licenses are compatible ... with the ODbL"[2]. With this in mind my modified data is of no use to OSM since my improvements can't be reincorporated with OSM? Is this correct or is there a problem with my logic? Many thanks.
