About this app

KartaView is a free and open platform for street level imagery. Anyone can contribute images with a smartphone and the open source apps.
After upload, KartaView will detect salient features from the uploaded images such as signs, lanes and road curvature. Using both new and familiar tools, anyone can then use these and other features gleaned from the images to improve OpenStreetMap.

Ratings and reviews

So, after a couple tries and reinstalls, whenever I click a blue line, it crashes with an unexpected error message (something wrong, try again later). don't know if that's because I'm not logged in but it doesn't work for sure if you're not

A nice concept, but the app itself is pretty poor. I often have "can't connect" errors when wanting to view my profile, the photos seem to be taken at a lower quality than the camera can actually manage, it won't let you delete a track before uploading, or even single frames, and it would be great if there was offline mode that downloaded which roads have already been photographed.

Works great! Simple to use. After uploading a track, you can see the status ("processing"/"reviewing") ont he phone or on the website. NOTE: After uploading there might be a short while where you can't see your track in the app. Just wait some minutes/hours and it will show up.
