I came across Mapillary this morning, and it looks quite smart. If you can get over the initial issues (need a smartphone, need some way to fix to bike/yourself, need a full battery) then it could make a great resource.
Like google street view for bike paths. It would be good for pointing out infrastructure issues round the city too.

Thanks, looks interesting. Took a look at St Andrews (the only coverage in Scotland), seems to work quite well.
Interesting to see how much coverage Germany had given that Google decided to pull Streetview from that country.Posted 9 years ago # -
See http://www.sotm-eu.org/en/slots/31 for a talk about Mapillary at a conference I was at recently. It's a fairly new project which only started in the past half year or so.
Most of my contributions are with my phone at shoulder height. I've had problems attaching my phone to my Brompton as the vibration of any uneven surface causes it to stop taking photos as they just come out blurry, yet my action camera doesn't have the issue.
It is possible to create photos using other cameras, assuming you can add the lat, long and camera direction exif data.
Germany has it so popular and are probably more accepting of Mapillary compared to Google StreetView due to the open license that the images are under.

Hi there,
we saw your thread about Mapillary at http://citycyclingedinburgh.info/bbpress/topic.php?id=13084 and thought this post might be applicable for Edinburgh, too: http://www.bodenseepeter.de/2014/07/01/how-to-street-view-a-bike-path-for-a-penny
I hope you find it useful. Let me know if we can help in any way to get more bike lanes mapped!

So having set my Sony camera on my handlebars to time lapse rather than video, I'm uploading Roseburn to Portobello. Had to crop slightly to remove my gps from view and have also had to copy GPSTrack tag data into GPSImgDirection (which is fair as the camera faces forward) using exiftool. Will hopefully see results by morning

Thanks @chdot - that's actually where I saw the app first. I wonder how well that design would handle Edinburgh's roads!

"Will hopefully see results by morning"
Yep

Someone has also done NMW but it's pretty blurry.
What happens when a route/place is done more than once, are images combined??

Multiple runs look something like this http://www.mapillary.com/map/im/R5kncLCUcKStIjC-1I4Ofw Seems to be you have to click on each individual track to select one to view and there is a lot of gps drift.
Ideally I'd like to see the images relocated by content to stitch them - you could effectively 3d map each pixel and build a full 3d streetmap if you had the processing power

Hi there,
yes, right now the algo for choosing what images to view next is most based on near-location and compass direction between images to left/right, and placing a high weight for staying on the same sequence for back/forth. We will experiment with better functions, and also work on filtering of navigation for e.g. time slicing, and hand-licking sequences, see e.g. here http://mapillary.github.io/mapillary_examples/index.html/peter

Also,
for bike mapping, action cameras like the Garmin VIRB are great, see http://blog.mapillary.com/update/2014/06/16/actioncam-workflow.html on a description on how to do it./peter

Would it be possible to upload images with only the GPSTrack tag rather than GPSImgDirection? It would need a user input for camera angle vs direction of travel but this should be fixed for a car or bike. That would then allow a direct upload from Sony action cams.
If also be quite keen to see a crop feature to remove bits of dashboard/bikes
