Tue Oct 6 13:46:54 UTC 2020

There is a list of available datasets and the proportion of existing/imported buildings for each municipality [1].

Apologies for omitting your name.  I hang my head in shame.

So the final result on the building import was the process and licenses are fine but local mappers need to agree with the import being done and if they do they can just go ahead but should follow the agreed process?

How many areas does the data exist for that haven't been imported yet? Perhaps there might be some interest in importing a few other areas.

Thanks John

Hi all.
The York Region is a component of ODB data import, which has been widely discussed and we all agreed that whole import process was acceptable. There is then no reason to go back to the import mailing list to do the discussion again. Look here [1] for the appropriate import procedure.

Speaking of buildings... In order to stay active during Covid-19 lockdowns, I have been working on a Covid-19 personal mapping project since mid-April. My objective was to map the buildings in Sherbrooke (ODB only providing 5% of the buildings).
After mapping around 30,000 buildings (according to an Overpass Turbo query), 80% of my initial goal is achieved. I keep moving forward with mapping and updating buildings and related features.

Best regards

There are two sources of buildings to import one is Bing the other is the stat Canada licensed one.  Both have the correct license for OSM.

If you are going after the stat can one then there was an import plan drawn up for Canada and that is in the wiki.

I suggest if you use the stat can import plan basically just copy it together with the license information or perhaps you can do a sort of amendment of it to cover York.  The reason I suggest that is there is an import mailing group that gets involved and they tend to ask all sorts of questions.  Getting by them has been described as the hardest part of the import process.

The original import was done in Ottawa and we got all the licensing permissions sorted out and because Ottawa is fairly small the local group formed a consensus that that is what they were happy with and that was the basis of that import.

When we set it up to import across Canada the problem with the stat can data was the quality varied from municipality to municipality and there was some concerns about if the data should be preprocessed in some way.  Also in some areas such as Toronto local mappers wanted to feel more in control.

I can't recall who came up with the preprocessing but I'm sure James will remember.  Pierre I'm almost certain expressed his opinion.  It might be worth looking at what they came up with and why.  I do recall that some mappers thought the Ottawa building import should have been preprocessed but the local mappers were happy with the raw data.

Hello,

I primarily map in York Region, Ontario, and I have noticed that the Toronto Building Import has been completed 3 months ago. Therefore, I am proposing to open a task on the Task Manager for York Region buildings, since having the buildings imported here would be nice. I'm not sure of the process on how to do that, which is why I'm emailing this group.
