[Talk-ca] OSM data quality in Canada

Hello list — My name is Martijn van Exel, I am on the OSM US board and work at Telenav. I’ve written to this list a few times before, but this time I am doing so with my Telenav hat on. Perhaps you know that we have the Scout apps (iOS, Android) which run on OSM data. (If you haven’t yet, plea
