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

Poor user experience, e.g. ☹️ can't delete junk images😡👎 Previous versions: recording randomly stops, shamefully useless message: "Recording had to be stopped KartaCam recording has encountered an error". No apparent error-reporting. ☹️First use was 5-min. ride; app captured 4 images at end. ☹️ No SD card support. Static text at bottom obscures control. Useless, waste of time; bad pre-beta must not have been tested on this OS/device. ☹️

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.

When touching a purple line in the app, it says 'nothing there', when tapping on blank area, it suggests pictures. Selecting single geolocated images like in Mapillary isn't possible. Uploaded a sequence a few days ago but can't find it anywhere. Can't delete single pictures before uploading. with these bugs, the app is completely useless
