This is rather discouraging and frustrating. When the Bing imagery was made available, I spent a fair amount of time cleaning up the maps in Aylmer, Quebec, a western suburb of Gatineau. Just discovered that my edits have been overwritten by another user importing CanVec data.
This import has introduced hundreds of errors: - Proposed and under-construction streets are shown as completed. - Streets are tagged as unclassified. - Service roads have been removed altogether. - Turning circles and traffic signals are missing. - Certain streets do not line up with high-resolution Bing imagery, and not in an off-by-a-few-metres way -- for example, the Bing image has a subtle S-curve, the CanVec data has a rather crude straight line bisecting the curve. This means that Aylmer now needs dozens of person-hours to get it back to where it was -- and at this point I'm discouraged enough to say the hell with this project and find something better to do with my spare time. Much of Ottawa is in a similar state: manual edits superimposed with CanVec imports that may or may not have been more accurate, and now there are two or three duplicates on top of one another. It's a mess, and it's in no way ready for MapQuest. I thought CanVec imports were frowned upon when there was existing road data? I'll tell you this: this is not the way to encourage people to contribute, if all the work we do with imagery is subject to obliteration by someone else's work with government vector data.
