This is fantastic! Great write up. A question: any idea what sort of accuracy you’re getting at the end of the process with respect to things like carriageway widths? As you allude to in the article, this could be a great tool for advocacy groups to identify where a road is wide enough to accommodate cycle lanes, or where footpath widths are substandard. I was just wondering if it’s possible to get the +/- 10cm accuracy that’d be ideal for doing this sort of work. Thanks!
