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!

I'll go out there later today and get an on the ground measurement and get back to you on this thread (and upload the blog post). > great tool for advocacy groups to identify where a road is wide enough to accommodate cycle lanes Agreed :D
- jakecopp 4y agoI added a section on taking measurements (under heading "Output accuracy: taking measurements"), it's pretty damn accurate! Large path: - OpenDroneMap: 4.54 metres - Tape measure: 4.56 metres Small path: - OpenDroneMap: 1.89 metres (though this varies slightly due to distortions) - Tape measure: 1.89 metres > I was just wondering if it’s possible to get the +/- 10cm accuracy I'm quite confident this is possible - maybe do a few sanity checks though!
- thomasbibby 4y agoBrilliant, thank you so much. Impressive numbers!
