Thanks for the detailed response and information. I am trying to work
with Guillaume Rischard who is trying to reach out to Kevin Bullock to find
an appropriate contact there to see what options are. This is new to me -
and want to ask questions before I say anything. It would be nice if they
shared back data that is derived from OSM or built into the dataset.
