Hi Daniel,
I had a brief look at project #173, task #20 and found that you can
either align the hospital with the underlying imagery or the houses to
the right of the task, but not both at the same time (Bing and ESRI bear
the same effect). This might have to do with different
projections/coordinate reference systems used by the data provider of
the buildings and the one used by the aerial imagery provider.
If we assume that the aerial imagery data is the correctly projected (as
we do as default in OSM, at least for Bing imagery), we would have to
correct the position of all the buildings according to the underlying
aerial imagery.
Furthermore, the buildings to be imported seem to have an odd level of
detail. Some are pretty detailed, some are missing details at all. I did
not only look at task #20 which you have already worked on, but also
task #21. Not sure if they were automatically collected or if a bored
intern had to do this - that would explain the varying quality.
Apart from the location of the buildings, you did a great job, I think.
Unfortunately, I am still working on two other projects in the tasking
manager at the moment, so, I most probably won't be of much help on
#173, but who knows, we are all grounded at the moment, aren't we?
Happy mapping,
Tim

Hi,
I completed more than a dozen tiles of the task #173 (Squamish). That
would be interesting if some of you could validate what I did so far, in
order to adjust the procedure if required.
Thanks.
Daniel
