Although if the community doesn't feel confident enough in this process, we could still revert to manually reviewing everything, but I'm trying to ensure a high standard so we don't need to do everything manually.

I'm all for doing as much as possible automatically, if we try to do it 
manually it's going to take forever.

I'm still working on this part of the code though.

It would be interesting to know how many addresses there are mapped 
already (and have far they are from the Vic dataset) as that would give 
an idea as to how much work there would be in resolving which one to use.

I think that your idea is a good compromise. Otherwise we have to drop 
the unit information or arbitrarily spread out a pile of address nodes.
