I'm happy to do it, but I don't think we're at the point where it's ready just yet. As others have pointed out, in terms of LGAs, - WA has three already in OSM of unknown origin, some don't match the PSMA data. I've added a changeset comment to try to determine if we leave those in place or replace them. - NT has one which is from 3 years ago originally from GA, which doesn't account for a new LGA from 2014, so I'm okay to replace this. - TAS have no LGAs in OSM currently - Chrismas Island/Cocos Island have no LGAs in OSM currently - SA has some LGAs, we'll just add in those missing and leave the existing ones in place - ACT is N/A - NSW already in OSM, so let's skip this - VIC already in OSM, so let's skip this - QLD has some rough approximations for a few LGA, I propose to replace these with the more detailed boundaries for Suburb/Localities, VIC has a lot of big differences so some local knowledge on that would be great, NSW is mostly complete, SA is just missing Adelaide. _______________________________________________ Talk-au mailing list [email protected] https://lists.openstreetmap.org/listinfo/talk-au
