So which ever source has the best resolution should be the one that stays, or perhaps a merge of the best data from both... OSM is a living entity that changes. Stewart, you've found an area of concern, and Andrew is responding.

So have a bit of a look into what CanVec is, and how the data has been sliced up and provided to OSM for consumption. You'll immediately understand what all these weird square boundaries are. Look just about anywhere in Canada where CanVec imports have happened. You'll find these artifacts all over. > Can't you run a simplification algorithm for closed polygons to get the > count down to something sensible? So, using that logic, should we take your Horne Lake closed polygon and simplify it down to 20 points? Okay, not entirely sensible, but then who defines sensible? Large complicated polygons abound in the OSM database. They just need to be dealt with appropriately. >> Just a thought could the missing data be a result of some user who did >> not accept the new terms of service > > No, the edits were me, or an earlier import from geobase_stevens from 2009. > > Please, as Daniel suggested, clean up your mess. And of course, thank you to both of you for all the work you guys ave done in adding to the OSM database. Everyone's contributions are appreciated, but occasionally we bump into each other.
