To give you a little more context, the OSM community is a bit wary of large
scale imports - it's quite easy for the data to grow stale, and minor
errors to accrue.
As a result, the OSM process tends to place highest trust on physical, on
the ground observations & multiple GPS traces, particularly of the road

Can you go into a little bit of detail around the processes you've used to
get to a high level of trust in the data? The data set does mention LiDAR +
Photogammetry, but I'm sure we'd all be quite interested to know a bit more
