Hi all, I have reviewed portions of 1998 changesets that had new roads added in South Australia at the time with only a handful of non-commercial editors creating highways.
Of 2673 new highways extracted by Overpass that were reviewed, - 77% appear to be private farm roads rather than residential or unclassified roads, - 6% appear to be alleys or lanes that should have their highway type reduced to avoid routing down the lane and - 2% had other issues. A further 3% were difficult to determine but caused no real concern including old road alignments that may have been reclaimed by the farmer. I reviewed each highway in JOSM using Bing / Maxar to determine what I thought each highway should be. My thoughts may not be the same as others on some highways however I believe I have identified the majority correctly without local knowledge. I have now altered the highways as indicated above and manually altered the 2% with other issues. This may mean there are a few islands of access=all, or where Right Of Way or livestock routes might have been set to private however I hope this is an improvement overall. Before embarking on a large number of additions, it might be worthwhile flagging this here and running some small batches. I am now seeing lots of changes in the Victorian high country by the same commercial team and removing surface type. It's hard to keep track of a very fast paced team making one or two edits in a changeset. -- Warm Regards Ewen Hill
