Tom 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 relation

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 open data

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 according to the "experts", but i

Tom 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 th

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 two

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.
