I think the Stats Canada project is evolving as Bjenk understands a little more about what he’d like and what we can do.
My understanding is currently he’s looking getting hold of the City of Ottawa building outline data and making it available to OpenStreetMap without the current license restriction. My feeling is the tile approach was an early one which won’t work as well as he thought. Some of the attributes he’d like, you just can’t get from Bing aerial imagery. He’s asking for a more disciplined approach than we usually do using a more standardised set of tags. Currently fire stations for example are often tagged amenity=fire_station and sometimes they have a building=yes tag. I think he’d like these to be tagged building=civic to be more specific than building=yes. So a lot of clean up work needs to be done. He’s also asking for the building outline to be tagged with the address including postcode. Which is interesting as currently each node of store within a building might have part of the address. Postcodes often are not present. If we decide to strip out the address other than the unit number from the nodes within a building outline we’d probably save a little database space. By the way we need an agreement on what to use for unit addr:unit perhaps? I’m not certain if he realises that 5-10% of our mappers make 80+% of the edits, often using JOSM so as long as he gives the attributes he’d like and we accept them then I suspect much of the work is done. However I understand the plan is to have a customised version of iD. Stats Canada traditionally has a sample file which is made available to field workers. I would imagine they will try to do the same here. A file which contains a list of building outlines which they would like enriched. One problem I see arising is a new mapper mapping to the Stats Canada guide lines using iD changes one or more existing tags. I do a fair amount of validation in HOT and some newer mappers either completely ignore or misunderstand the instructions. I’ve heard two comments so far from professionals working in the GIS / Open data fields, one was they didn’t think it would work, Stats are asking too much. The second was more guarded they thought it could work and it would certainly be interesting to watch. I would tend to agree with the second one, it will certainly be interesting to watch.
