Hi Andrew, Just to add what others have said already,
> OSM adoption is largely dependent on a minimum correlation between the OSM ways and the streets found in Government centerline/road datasets (States and/or LGAs) Could you elaborate on what exactly you mean by that or what specifically you're aiming to achieve? For example could you use a map matching algorithm to match OSM data to other road network data but since there will always be differences between multiple datasets that's never going to be perfect. Graeme mentioned on/off ramps, but more generally there could be differences in how the centerline is represented. For example, OSM splits ways where there is a physical separation, so you might find other datasets just have one centerline, but OSM would have two parallel ways for each direction. The transition between these two modes is never ideal either. This isn't saying one is necessarily wrong but rather have different guidelines on where the line should be drawn. The other consideration is that most states we only have access to GPS or satellite imagery to derive road geometries from so the geometry accuracy in OSM isn't necessarily as great as survey grade data.
