“Whats up with the forests in Canada?” A wiki page is a good idea! And while talking about forest in eastern Canada…
It would be very helpful to have a plugin in JOSM that deals with Canvec water/wooded area integration in multipolygon. I am not really a developer but since the merging operations are repeated over and over again over large areas... might it be possible to do something? On the same topic, it has been suggested to split wooded areas in smaller chunks by using features on the ground as outer limits (mostly roads, streams, rivers) and get rid of arbitrary rectangles from Canvec. Is it something we are aiming at?

(http://worstofosm.tumblr.com/post/22180046353/dear-openstreetmap-isnt-it-strange-how-the). As someone who spends a some time amount of time in some of relatively unpopulated areas of Canada and makes an effort to check the quality of Canvec data (which is usually pretty good), I do agree that it is impossible to do everything to the same level of quality that we would provide in Toronto or Timmins or even small prairie towns. One of the things that seems to bother Nakaner and the WoO people (if I may put words in their mouths) is that the boundaries are a bit funky in Canvec. Forests, lakes and wetlands spill into each other, and they are often out of alignment with the Bing imagery. In some ways this reflects a degree of natural ambiguity: if we look at the above Hudson's bay coastline, their is hourly variation in coastlines, and even the long term patterns change over time. The Manitoba-Nunavut boundary is more or less fixed by so we can't correct it, and a glance at satellite imagery shows that the vegetation tends to be spaced off of the shoreline. That being said sometimes there is some weird stuff happening in Canvec data that is out of sync with what is on the ground. These should be corrected when detected, but are rare enough that they shouldn't be a problem. I confess I haven't always been great in following the rules when doing imports (I think the last few years I've been fully in compliance), and have sometimes caused problems, people on this list have generally understanding. Perhaps we need to have a "Whats up with the forests in Canada?" page on the wiki to explain our situation and how we've tried to deal with it. _______________________________________________ Talk-ca mailing list Talk-ca@openstreetmap.org<mailto:Talk-ca@openstreetmap.org> https://lists.openstreetmap.org/listinfo/talk-ca
