Hi ftcat, thank you for confirming this junction accurately follows the junction=roundabout tag according to the OSM wiki (junction=roundabout). Happy mapping!

Hello ftcat. I changed the main roads through the Agricultural Showgrounds to unclassified based on them being a distributor road (highway=unclassified). However, I will leave these as you have classified them. Best.

Hi, thanks for the question. Apple has an agreement with Digital Globe/Maxar to use their more recent imagery to edit OpenStreetMap, which is not publicly available for editing OpenStreetMap. We generally use the imagery that is already available in JOSM but where we do use that more recent imagery, we always cite it and the date of the imagery is from in the changeset source. Have a good day.
