[Talk-ca] Adding buildings.
OpenStreetMap is highly decentralised which is both one of its strengths and also one of its weaknesses. There are a number of sources of building data, the first is an experienced mapper adding in buildings with something like JOSM and the buildings_tool plugin working from Microsoft imagery. Esri, and Maxar and Mapbox satellite imagery are also available. That one is the least contentious and is acceptable to everyone. Second is iD which is the default mapping tool on the OSM web page. You can map buildings accurately with this one but in inexperienced hands you get some very poor results. Pierre noted in disaster mapping with new mappers the results were really very bad. There is something called a mapathon where inexperienced mappers are invited to map. Yes it gets a lot of data into the map but the clean up effort required afterwards is fairly horrendous. Stats Canada pilot project was going to be based on this until they were persuaded to go Open Data and use the City of Ottawa's Open Data and the import process. In Ottawa today practically every building has been mapped and has the correct address. There are one or two new buildings that haven't yet been added to the map. It took a fair amount of effort and organisation and included help from Mapbox. One problem was the license for the data. Toronto has Open Data but the license has not been confirmed to align with OpenStreetMap. Although there are guidelines the authoritative body in OpenStreetMap is consensus of the local mappers. So Ottawa local mappers decided the import could go ahead, were very involved in it and were happy with the data quality. We'd seen iD mapping of buildings before and the City of Ottawa data was fairly good. After the pilot there was no serious money available at Stats so the second part was going to be "community led". They managed to talk to various municipalities to allow them to release the municipality data under the Stat Can license. Following a discussion in talk-ca I put forward the formal import plan. The data quality was different for each municipality and was questioned. Normally you look at the client requirements to see what is required. This is something that OpenStreetMap very rarely does. Mappers basically map. Each has their own individual standard of what is acceptable. For your purposes if the angle of the corners isn't quite 90 degrees it really doesn't matter. What you're interested in is something within two meters of the right place. However consensus requires agreement from everyone. However the problem for you is the local mappers in Toronto and I assume York would like a higher standard even if it means fewer buildings get mapped. Today we have two other sources of building data that could be imported. One is the Microsoft building data and the other is NR Can LiDAR data but neither are much use without the local mappers support. Some courier companies have hired mappers to add data to the map. Bangladesh is one area where this is done. Some are very good, some are not so good. I don't recommend this route, one danger would be they'd just import the Microsoft buildings and charge you for mapping then someone would challenge the data and have it removed. If you have a specific problem area email me directly and I have been known to add in buildings with JOSM. Once we get the building outlines added then adding the address is fairly simple with a smartphone and something like StreetComplete. Also Stats Canada has address information that can be imported. Does that help clarify and define the problem?

Hey Russell / all, I performed a rudimentary test of an address in the map without a postal code and later used the Nominatim to search for it to see what it produced. The address was 27 Cairo Street in St. John's, NL - I used this because it is an old address of mine and I know the postal code there without reference to Canada Post or the like. The result from Nominatim is A1B 3X9. The actual postal address is A1C 4X2 - a significant difference. I don't believe that the postal data in Geocoder is particularly accurate.

One thing to remember about postal codes is that they are a delivery mechanism first and foremost. Unless Canada Post has changed things, they don’t have a location, per se, because they’re based on postal walks (the route the postman walks). Most postal codes refer to something like 11 dwellings, except in the cases of large volume receivers (apartment buildings and large commercial receivers) and rural postal codes, so any spatial reference is rarely going to be 100% spatially accurate.

[Talk-ca] Adding Buildings + Leisure + Corrections To Ottawa Map Over Holiday Season
Hi Folks, I've created a new mapping task for the Ottawa area [1]. I really want to make our local map super awesome:) I see adding buildings as one of the biggest projects we can undertake, so that local mappers like myself could start adding address data from local surveys. The task focuses on buildings and leisure areas but also asks those mapping to correct any obvious issues encountered. I understand it's a large area to map but I see this as a long term project. It's also something I'd like to use to encourage new local mappers to get involved with through our monthly meetups. Let me know what you think and if I'm missing anything in the instructions to make this easier to work with! Join me over the holidays:) Cheers, Richard [1] http://tasks.osmcanada.ca/project/9 -- Please note: I only check email a few times during business hours.

Re: [Talk-ca] Adding Buildings + Leisure + Corrections To Ottawa Map Over Holiday Season
Fine with me. I've been mapping apartment and commercial/institutional buildings but not ordinary residences in my area. Does that seem like a reasonable priority, with the rest to be added later?

Re: [Talk-ca] Adding Buildings + Leisure + Corrections To Ottawa Map Over Holiday Season
It sure is -- as long as the postal code is coming from an appropriate source, e.g. a store receipt, a business's homepage, or your local knowledge. Maybe a note about that fact could be added to the instructions. Harald.

You might like to add in a few footpaths from Bing and compare the city's cycling map to ensure that paths in parks are correctly tagged for cycling.

Re: [Talk-ca] Adding Buildings + Leisure + Corrections To Ottawa Map Over Holiday Season
Hi Folks, Thanks so much for the great feedback! Update: - I've removed the mention of postcode collection. I'm not sure of the legal aspect of collection as raised in an earlier thread. - Add several priority areas to help focus the mapping. - The generated tiles are the smallest the task manager will provide through the interface. There is an option to further split the tiles when a task is selected for editing. When you click Start Mapping, underneath the drop down for editor of choice is Task to big? Split. Click this to subdivide the tile further. Really excited for this:) Again, thanks for your feedback and help! Have a great afternoon!
