While reviewing edits in my neighbourhood, stumbled on a lot of edits by a new editor called StreetComplete. Streetcomplete seems like an open source map editor on Android to quickly add missing metadata to OSM around your location like streetnames, road surface opening hours etc. using a simple form based UI.
Curious, I listed all the changesets from StreetComplete using osmcha and was surprised to find over 30,000 changesets since the first one in Nov 30 last year. Just yesterday, there was 2,700 changesets uploaded, so there seems to be a sudden surge in editing activity.
The edits in my city were mostly adding the road surface and looked quite good, and its exciting to see such well designed tools driving new contributors to the map. If you are curious use osmcha bbox filter to review edits from StreetComplete in your area and share any observations on the editing activity.
