Anyway, I think what Richard is trying to say is this: 1) Create osm-without-australia.osm by removing australia from the OSMF database. 2) Create fosm-australia-only.osm by removing everything but australia from the FOSM database (for both of these extracts, use a boundary definition that's PD. 3) Make a zip file planet-combined.zip with the two files. *That* would be a collective database. 4) Render tiles from osm-without-australia.osm and make them CC-BY-SA. (*) 5) Render tiles from fosm-australia-only.osm and make them CC-BY-SA. 6) Delete tiles so that remaining tiles in australia come from 5, and remaining tiles outside of australia come from 4. For tiles which overlap (mostly water and zoomed out tiles), pick one (randomly, from one or the other, based on whether it is geographically more in/out of Australia, based on which tile contains more elements, whatever).
(*) I'm not 100% sure 4 is allowed by the ODbL. But most people claim it is. _______________________________________________ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au
