Re: [Talk-ca] BC2020i Mapathon Event
These tips are much appreciated. My apologies for the misinformation about your involvement with the folks at the Taskar Centre. We have the call out for local OSM Task Manager volunteers and are hoping to recruit them asap. Fleming College has an excellent GIS program as does Trent University. We are also hoping for support from the Toronto OSM folks.

[Talk-ca] Building_Canada_2020
The wiki talks about grand ideas. https://wiki.openstreetmap.org/wiki/WikiProject_Canada/Building_Canada_2020 But what it doesn't do is give examples of how to enrich the building outlines. When I spoke to Stats Canada it was the enrichment that was the most valuable How many churches are there? How many apartment buildings? How many levels (floors)? How many care homes etc. WiFi available? Website? I'd think in terms of streetcomplete an android app for filling a lot of these gaps but there are other software packages around such as Vespucci on android, iD on whatever iD runs on. JOSM but you need someone present who knows it. It is excpetionally useful for accurately drawing building outlines though. I don't know what school students at various grades are capable of. I think the wiki page would be more useful if it listed what enriching details would be useful and how to tag them. I would suspect that printing out a map with the buildings on it so notes could be made in the field might be useful. Thoughts? Anyone with some expertise about what works for a mapathon with students? Thanks John ___ Talk-ca mailing list Talk-ca@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-ca

My thinking here would be: 90% of the value of what you produce will be in the surveyed stuff - as John said, number of levels, type of building etc.; what he didn't mention but what certainly could also be interesting to some is the 3D modeling tags like roof shape information which will make the building look nicer on 3D maps. If 90% of the value is in the "handmade" stuff anyway, why even depend on an import for the remaining 10% - isn't there aerial imagery from which you can trace the building? With proper tooling this is quick and painless, and a student who has actually "drawn" the houses will feel much more pride in the resulting map as one who has simply taken existing data and uploaded it to OSM. One is a creative task, the other just data mangling. I'm pretty sure students would warm more to the creative task.

Re: [Talk-ca] Manitoba buildings, addresses and high school work
Looking at Brandon in OpenStreetMap many buildings are mapped but there isn't much detail. Stats was after things like the number of levels, house number, street name, is the building commerical, residential, apartment. There are some 70 or 80 different tags used for buildings in taginfo. At the bit of Brandon I looked at there were only two values used. It was also after amenties such as cafes etc. These are all things that can be added with tools such as street complete. Because you are adding tags to enrich the existing data you are unlikely to to draw a building in the wrong place. I'd go after enriching the existing data first before thinking of importing more buildings.

Re: [Talk-ca] BC2020i Mapathon Event
Got it. Thanks, James. On another note, we are still looking for 8-10 facilitators for our March 29 mapathon in Durham Region. I approached the Toronto OSM and will follow-up with them at their next Meetup on Monday. I also let the Peterborough chapter of GoGeomatics. The challenge is that the colleges had a lengthy strike in the fall and have no time to participate in extra-curricular activities this year.

Most worryingly, it requires that the person using/importing the data on behalf of a legal entity has the capacity to legally bind that entity. In short, it means that if we import the Brandon data, we agree that we have the legal capacity to respond to anything that Brandon could choose to throw at us. Not one of us has that.
