<p>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!</p>
<p>If anyone is interested, I've documented some open-source code
for cleaning up building geometries for another import:

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

<div dir="ltr">Why is it that FME seems to be a tool that's OK to
use for OSM when someone replied that they could use PostGIS and
was shut down by someone else replying 'I'm not installing
postgesql for you to accept simplification'? Does anyone else
find it a little ironic that the community would move forward
with proprietary software over open software? <br>

good dialog ensues. Municipality by
municipality, in conjunction with BOTH the
StatsCan and Bing data, the right things are
getting noticed, the right things are getting
human-realized at what the next steps are to
do. It gets better.<br>
<br>
Yay. Stitch it together. One municipality at a
time. One province at a time. Pretty soon,
after a few revisions of data and
back-and-forths between municipalities and
province-wide data checking, you've got
something. There, you go.<br>

they may have to do another few tries, or maybe
retain their Neural network. - Is there anywhere
where the Bing data looks nice? I found burbs in
Winnipeg not bad, but there's some really weird
elements when the source data is too simple
(buildings in the middle of fields) or too
complex (urban cores)
