[Talk-ca] Aylmer/Hull QC: CanVec import overwriting existing edits

I've been in contact with the user who did the import, and referred
him to the list. He's posted here before. My impression is that this
was a well-meaning import with unintended consequences; I'm not at all
comfortable with the talk of "vandalism" on osm-talk that was spurred
on by tweets I made yesterday.

I appreciate the problems about CanVec imports and quality, James.
I've spotted areas that had road data that, on closer inspection, were
horribly problematic: they were added, presumably, before
high-resolution Bing imagery became available for that area. They may
well have been good candidates for wipe-and-replace CanVec imports,
but from a great height the areas probably looked okay. (I only
noticed them because I was familiar with the area and wanted to see if
there were a few things I could add to existing edits, and then got
sucked in for an hour and a half doing my best to straighten roads and
railways, correct intersections, add parks and parking lots, and so
on, and so on ... )

The data imported in Aylmer/Gatineau/Hull is in point of fact more up
to date than the Bing imagery, and adds new roads that I would have
had to go out with a GPS to trace (no sooner than spring). It also
adds addr:interpolation data, which is useful. But on balance ...

I don't know how to revert and I've never used JOSM. Map-wise, I have
a lot of things on my plate. I've been quite happy to trace imagery
and to walk around with my GPS and upload the tracklogs, but I have no
interest in mucking about with CanVec imports.

Which is to say that I'd very much appreciate any assistance in
getting all of this cleaned up. I believe the importer could use some
assistance as well.

I don't suppose we could keep the CanVec addr:interpolation ways with
the previously traced streets?
