[Talk-ca] BC2020i and Wikidata

Thanks, John. We’ll discuss this at our June 8 planning meeting for the Sept 28 Durham Mapathon 2 event. Where municipal staff identify a policy challenge and engage students in applying their local knowledge worked well on May 3. Maybe Keith can share what he learned working with high school classes in Manitoba using the BC2020i framework.

I think it depends on what you are trying to do.  There are two parts to BC2020i the first is map the buildings the second is enrich the buildings with tags.

The first part can be done best by importing Open Data if the licenses align and at the moment few do and of those that do not all have accurate building data suitable and even if they do it needs specialist knowledge to know all the steps and to do the import.

It can be done with mapping from imagery but whilst mapping using the building_tool plugin in JOSM does work well in a mapathon environment using iD seems to give rise to data quality issues and you don't really want to offend to many OpenStreetMap mappers too often.

Enriching the tags of existing buildings probably doesn't look so interesting to students but it really is of value especially if its local since the sort of number of levels of the building cannot be seen from imagery that we are licensed to use.  Even in Ottawa there are many areas where although we have all the buildings we have many without tags saying how high they are etc.  I'm not even sure we have a list of what would be most useful.  Streetcomplete an Android app is very useful for adding data.

Locally we have houses that are split level, so a garage in the basement with a room over the top but the rest of the house is single storey.  I'm not sure how these should be tagged.  Is it documented anywhere?

What might be interesting is to get them to pull OSM data into R R.org and do some analysis and that might be valuable in places like Africa where they have the same problems but fewer resources.

Has anyone thought of using Wikidata to enhance the BC2020i project work with secondary and postsecondary students?  https://www.wikidata.org/wiki/Wikidata:Main_Page
How could structured, linked open data help municipalities and regions engage students in collaborative research projects? We are exploring ways to build on the Durham Mapathon event of May 3. At that event, Durham Region staff collaborated with senior secondary school teachers and students from Clarington Municipality on policy challenges. The Durham Region GIS staff provided the technical support.
