Re: [Talk-ca] 2020 building import wiki comment by Nate Wessel

John, I'm sorry to keep saying this, but I really do not think this is an acceptable import approval process. You're saying there was no wiki describing the plan when this went to the imports mailing list - only a link to a similar plan with related data. You did not follow the import guidel

Hi Yaro, Thanks for marking this as on-hold in the tasking manager. I know I came in like a wrecking ball and I really appreciate y'all holding things up while we discuss. I'd be happy to validate data and help import the rest of central Toronto once we're up and running again! I use the dat

I'm not familiar with the tool, but that is essentially what I'm asking for -  nothing all that complicated. We would need to make sure we're not losing any valuable detail though, and ensure that topology is preserved where buildings share nodes. Nate Wessel Jack of all trades, Master of Geog

Re: [Talk-ca] 2020 building import wiki comment by Nate Wessel

I agree and we are sensitive to Quebec's position. I think the hope was we would make the data available and that local mappers would be involved in the import over time as happens with CANVEC.  One comment I heard early on was this isn't so much an import as a marathon. What seems to have h

Re: [Talk-ca] 2020 building import wiki comment by Nate Wessel

I found the building footprints to be very good. JOSM cleaned up most of the errors..I'm not sure it would be worth the risk to do more processing. Sometimes there were crossing ways, usually with terrace or buildings in the downtown core that need to be fixed manually. Which took a ton of time. I

Re: [Talk-ca] 2020 building import wiki comment by Nate Wessel

I'm on board with removing redundant nodes, as long as it doesn't affect actual geometries much. Also there are quite a few duplicated nodes in buildings. They can be removed in JOSM in one click before upload but better to do it at the source. On Fri, Jan 18, 2019 at 4:25 PM James wrote: > I ca

With default settings in JOSM, sure. In the import I was working on, we used a Douglas-Peucker algorithm with a 20cm threshold (before the import started) and it worked beautifully. We had many points that seemed to have been introduced in the shapefiles as some kind of data artifact - they did

John, You seem to be playing the long game with this data - it sounds like you've been working with this a lot longer than I have, and you've put in the time and effort to help make this actually-quite-incredible dataset available to us. I don't want to stop the import from happening - quite

Jarek, There is no question we want this data. I went through much of it in Toronto and Kingston and I found it to be very good, consistent and precise. Time-wise it's somewhat current with 2016 ESRI imagery (sometimes ahead, sometimes slightly behind) and is well-aligned with it. It offers 3D feat

Re: [Talk-ca] Ongoing Canadian building import needs to be stopped, possibly reverted

Nate, I'll change the project name to reflect that the import is on hold. As a local mapper, if you want to take a lead on the Toronto import that'd be great. I did review some of DannyMcD's edits last night (Mississauga-Brampton-Vaughan) and to be honest was rather disappointed with the quality. I

Re: [Talk-ca] Ongoing Canadian building import needs to be stopped, possibly reverted

Some more thoughts from me. Building outlines, particularly for single-family subdivisions as seen in Canadian suburbs, are extremely labour-intensive to map manually. My parents' house is now on OSM - accurately. They live in a city with about 10,000 buildings, and about 0.5 active mappers. This
