[Talk-ca] Building Import

[Nate Wessel]

I agree that the use of closed software for this is not ideal, though I 
think it's far from the most worrying thing about this whole process. 
Perhaps that says more about the rest of the process though... I'm glad 
we're at least talking about cleaning up the data now!

If anyone is interested, I've documented some open-source code for 
cleaning up building geometries for another import: 
https://github.com/Nate-Wessel/hamilton-import

Some of the same PostGIS scripts could easily be reused here, especially 
the simplification step, which takes account of any shared walls.

Best,
