<p>Responding to point C below,<br>
I would strongly suggest that we not confuse the process of
importing new data with that of updating/modifying existing data
in the OSM database. One of the things I really disliked about the
initial building import was that it overwrote existing data at the
same time that new data was brought in. These are really two
separate import processes and require very different
considerations. <br>
</p>
<p>We can certainly consider using this dataset to improve/update
existing building geometries, but I think that is a separate
process from the import we are discussing here. To keep things
simple for this import, I would suggest removing any building from
the import dataset that intersects with an existing building in
the OSM database. That is, let's not worry about conflation for
now, and come back and do that work later if we still feel there
is a strong need for it. <br>
</p>
<p>I see the main point of this effort as getting more complete
coverage - it we want to use the dataset to do quality assurance
on existing data, that is a whole other discussion.</p>
<p>Best,<br>

<p class="MsoNormal">Thank you James, I really appreciate your
offer (and that of others). So yes, I think hosting
pre-processed data in the task manager, for approved regions,
is an attractive offer. When we agree on a municipality for
pre-processing, I will contact you to make the data available.<o:p></o:p></p>
<p class="MsoNormal">BTW, I thought ODB data in OSM format was
hosted with the OSMCanada task manager. I understand that ODB
data are currently converted on the fly when requested?<o:p></o:p></p>

work units for import:<o:p></o:p></span></b></p>
<p class="MsoNormal">I agree with Nate, ~ 200 buildings or ~
1,500 nodes would be suitable. I was thinking at the same
importation rate, but for an hour of work. It seems best to
target 20-minute tasks.<o:p></o:p></p>
<p class="MsoNormal"
style="margin-bottom:0cm;margin-bottom:.0001pt"><b><span
style="font-size:12.0pt;line-height:115%">c) Task manager
work units for checking already imported data<o:p></o:p></span></b></p>
<p class="MsoNormal">According to Nate, it is definitely not
faster than actively importing. We should then keep the above
setup (b).<o:p></o:p></p>
<p class="MsoNormal">However, what if I add a new tag to
pre-processed data indicating if a building was altered or not
by the orthogonalization (and simplification) process? For
instance,
<i>building:altered=no</i>, would identify buildings that were
not changed by the process and that could be left unchanged in
OSM (i.e. not imported);
<i>building:altered=yes</i> for those who were changed by the
process and that should be imported again. The same
pre-processed datasets could then be made available for all
cases. Thoughts?<o:p></o:p></p>

<p class="MsoNormal">I agree with Nate’s suggestion to try
contacting the top 10 mappers in an area. Using the "main
activity center" would work for most of the contributors but
selecting other overlays (.e.g. an activity center over last 6
months) could also work great. As long as we identify who
might be interested in knowing there is an import coming.<o:p></o:p></p>

the proposal on c)<o:p></o:p></p>
