Dear Janko,

I have been dialoging with Christopher Beddow, Edoardo Neerhut, and Fredrik
Glans at Mapillary over the past couple of months. While all three of them
have shown enthusiasm, single-snap images are just not a priority at this
point for Mapillary.

Yes, I confirm - nearby images whether mapillary, flickr or wikimedia
commons are rarely of any use. Also, image quality for our purpose has much
more to do with image cropping and lighting than the number of pixels in
the image.

For the European Water Project we have integrated into our Progressive Web
Application the ability to allow our users to take images of the drinking
fountains and cafés (osm nodes & closed ways) already displayed in our
app.  We use the mobile camera webrtc, add the mobile phone exif data, and
then store the images on our server.  Our goal is to move all our images to
wikimedia commons.

Here is a video of how the image capture works.


here is a sample of some of the images taken with our app

Best regards,
