[Talk-ca] Buildings in Ottawa after the Statistics Canada project. BC 2020?
These are very much round numbers and it depends a little exactly what you count as Ottawa. We have some 300,000 ways mapped as buildings, 280,000 have addr: house numbers and street names. I think the majority have been imported. Nominatim will find buildings that do not have a street name associated with them but unfortunately I think finds the nearest street to the building which isn't always the correct one so its better with a street name even if it does fill up the database. building=yes is 50,000 so 83% have been better classified which is good. Some 8,000 have building:levels, these have to be added manually. So shall we say 3% have been mapped by mappers on the ground. Retail 3,000 commercial 4,000 garage 6,000 There were 179 labelled detatched so I corrected them to detached 1600 had a web site. Someone with overpass could probably come up with more accurate figures but to my mind we didn't managed to get as much additional detail on the buildings as I might like. I'm still unsure how a split level building should be mapped. Terraces are sometimes mapped as individual units, sometimes as a block with address information for each unit. Should bungalows be tagged building=detached building:levels=1 or building=bungalow remembering that locally there is a terrace of bungalows. I think the project needs some guidance on these points along the lines of the OSM African highway wiki if the data is to be useful.

Re: [Talk-ca] Fwd: BC2020i - update Sept 2018
Matthew, I personally thank you for sharing Alessandro's missive with talk-ca (an OSM-based list).However, Alessandro mentions "BC2020i" (and even "BC2020i-2"), initiatives which "used" (or proposed to "use") OSM as a data repository. Not wishing to rehash history about this yet again, the initiative was found to not fully respect some basic tenets of OSM (primarily that process and importation of data be "Open") and a genuine attempt was made (partly rather publicly here) to re-imagine a re-branded project (BC2020, no "i") which more openly and harmoniously integrated with a wider OSM community using familiar and more-open communications channels like our wiki and this talk-list.As Alessandro didn't mention OSM one single time in that message, yet it was forwarded to this list, I remain quite curious what role OSM is to or might play in any "BC2020i-2" initiative. So, I invite / politely request Alessandro to post here exactly what that is or will be. Is it a national-scale import of the Bing building data (as he says "what they did in the US")? I realize that from STATCAN's and indeed a much wider Canadian perspective, this "initiative" will be much more than that, benefiting many, and for that I do share enthusiasm. Still, I ask the specific question from an OSM perspective: what role will our mapping project play?Please, Alessandro, address OSM directly (in this list) what OSM is to BC2020i-2. You might start by addressing what is wrong with BC2020 (no i) as it exists in our wiki and how BC2020i-2 might diverge from that, but I'd prefer you explain it to us, rather than me guessing here in talk-ca.Regards,Steve AllOSM Volunteer since 2009 ___ Talk-ca mailing list Talk-ca@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-ca
