The OSM community worked through the locations which were flagged as missing in OSM and added them into OSM, it wasn’t a perfect comparison between the two datasets but we’ve captured most of the low hanging fruit. This was done through MapRoulette.
There were a number of instances where the location of the TfNSW data was a fair bit off the actual location and where we manged to correct these we’ve added the reference number in OSM so future comparisons can easily pick these up.
We haven’t brought across all the reference numbers into OSM, only those locations which weren’t found in OSM now have the reference numbers.
