noticed was that some of the buildings are duplicates. I assume this is
part of what you are talking about when you mention internal CanVec
conflicts. In the case of a local public school, I deleted one of the
copies and
As a geocacher, I'm unhappily aware that different brands of GPS give
different results, with differences in the order of 10 meters for an
individual point. I suppose a track should be better, since there is an
internal consistency check, though not if the difference is due to
systemic causes.

Tom,
Differences in GPS results has less to do with the GPS brand and more
to do with how the GPS is used, the type of antenna, the satellite geometry,
WAAS reception, etc. If you placed your consumer grade GPS receiver in the
exact same location on two different dates you will get

I have a Garmin Etrex HCX. I had the opportunity to compare my results while
hiking with a friend wich has a Garmin GPSMAP 62. The antennas seems to make
the difference, especially when there is a coverage in forests.
Even with the same brand you may notice differences. When opening
A really simple answer that gets lost is this:
Did you make the edits to the best of your ability, and your edits add value to
the OSM project?
If so, then it was the right thing to do.
We all bring different levels of ability, and may not do things perfectly

I was looking at Helsinki for solutions to a lane mapping problem (how
to map left turn lanes), and noticed they have bus routes specified as
relations on the road segments. This put me in mind of Ottawa. My first
thought was to check on copyright issues. I learned that Ottawa has an

this Ottawa license seems compatible with ODbl. Then, I think that the data can
be imported. You can add to the relation the tag source=City of Ottawa.
I have not done any yet, but it does not seem to complicate. Wiki pages should
give godd information. Also, looking at some Bus

I was actually thinking of something similar for the Region of Waterloo,

Waterloo license is based UK Government's Open Government Licence and is
considered as a true OpenData license. It is not the case for all canadian
