The wiki page currently has a very wide range of information which might be too much for a casual mapper to digest.
https://wiki.openstreetmap.org/wiki/WikiProject_Canada/Building_Canada_2020 There are two parts mapping the building outlines and enriching the data. Since the project has started many things have changed. Stats has managed to make a slew of building outlines available under the federal government's Open Data license. Microsoft has released a large number of building outlines in the US and I think it's a fair assumption that they will be doing the same for Canada within a reasonable time frame. These are both high quality data sets but will need verifying when imported. My personal view is it is probably better to use these sources first than to have mapathons with inexperienced mappers tracing buildings using iD. In Ottawa we managed to enrich the tags on the buildings. 117491 detached 64173 house 59942 terrace 47997 yes 8204 residential 5757 garage 4147 commercial 2762 retail 2601 apartments 1551 barn 1420 shed 892 school 788 industrial 544 roof 488 static_caravan etc and we have an average of 3 to 4 associated tags on each building such as building:levels etc. https://www.jatws.org/johnw/ottawabuilding2018oct.zip and I think its this enrichment of the data where we can best use local mappers. It would be fairly simple to have a graph showing how many buildings have been mapped and tagged for a particular region. Would this be useful? There are some CSVs in the zip file above if anyone wants to experiment. Should we try to tailor the information on Building 2020 towards inexperienced mappers to make it easier for schools etc to get involved? What would be most useful? Thoughts please Thanks John
