[Talk-ca] BC2020i and Wikidata

[john whelan]

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.
