I've occasionally used the CoMaps OSM editing capability to just get the basics in before doing the big work in JOSM, or more likely the web editor. Now I'll be looking into MapComplete much further.

I'd also strongly endorse its on-the-street mobile app counterpart, StreetComplete. Splitting stuff into tiny tasks you can focus on really helps if you're just out on foot in an area.

Similarly, `Go Map!!` is an iOS app that makes editing OSM data easy.

Adding missing features is one of my favorite things to do while traveling, and feels like a way of giving back (“take only photos, leave only GIS traces”?)

thanks!

For start StreetComplete is an Android app unavailable (for now) elsewhere.

MapComplete has multiple in-depth layers, while StreetComplete is more general.

StreetComplete puts more focus on being usable out-of the box for newbies, while I would describe MapComplete as having focus on usability but allowing deeper dive in specific topics.

(disclaimer: I helped with developing StreetComplete)

Streetcomplete can filter the map with a variety of filters for features you can edit or complete(Street lighting, Surfaces, Sidewalks, Bike paths, Street parking, Addresses, Places, Things, Buildings). Plus there's some specific "quests" where you can complete information for specific POI ("Does this bench have a backrest? Yes|No", "Where does this fire hydrant lies? On the grass | On the roadway | On a walkway | On a parking).

Mapcomplete also offers filling info about existing POI, but you can filter on specific theme (Drinking water, sports) or very specific theme (etymology) or even your own. There's also an UI to add new POIs; I don't think it's possible with StreetComplete.

Either way both are great.

I've been in and out of MapComplete since this arrived on HN and have not had any such problems.

Yeah, it's definitely super slow right now.

I use the app "flush" for this, and it works pretty well.

You can login with an OpenStreetmaps.org (osm) account and edit it yourself. This app is used to add those objects. There is also an app "StreetComplete".
