Hi Robert, Thanks for this. It's great to have some concrete analysis of what we did, and the extent to which it's accurate.
Is there a full cross-tabulation available of the numbers for building-osm-status vs building-true-status? In the report there's a table of over/underrepresentation, and some other stats, but it doesn't give me a complete summary of whether our errors were in the form of "bias" (e.g. consistently labelling things worse or better than they are) or "variance" (e.g. the labelling tends to be a bit random). I'd be really grateful if you could provide the full cross-table.
