ODbL? here's a interested case https://www.gislounge.com/gis-data-high-resolution-global-hydrography-dataset/amp/ are they allowed to share this on CC4? Shouldn't it only be ODbL? are they allowed to share only after a registration? anyone wanna try getting a copy of the derivated work as they need to without registration?

If you took only what is not in OSM, I guess it wouldn't (no data > from OSM contained). So the set operation chosen (difference or intersection or any other) decides on the legal status of the resulting data set? You are aware that a difference is the same as an intersection with the complement, i.e. A \setminus B = A \cap B^c - see: https://en.wikipedia.org/wiki/Complement_(set_theory) -- Christoph Hormann http://www.imagico.de/ _______________________________________________ talk mailing list [email protected] <mailto:[email protected]> https://lists.openstreetmap.org/listinfo/talk
