You can and you should contribute - Open Street Map
Today I found out that it's actually a lot easier to contribute to Open Street Map than I thought. There are some serious gaps in house addresses in my area and I was painstakingly using the built in browser editor in the browser.
But, you can use a FOSS app (available on fdroid) called StreetComplete that makes it a lot easier to help out filling in the gaps in your local map data.
It's really fun - kind of like Pokémon Go but you are actually making an impact 😁
Hmm. I dislike that it uploads every thing as a separate change. I much more prefer editing the whole area and saving it as one neat package, rather than posting hundreds of "this is road is made of asphalt" posts.
So it's not for me, but if that helps to make OSM better, I'm all for it!
Maybe I could make a separate account without neat history and from time to time click some icons in the app though. That probably wouldn't bother me as much.
it doesnt close a changeset after every single change, at least it shouldnt.
mmv but if I close the app for some time it bundles my changes in one OSM set
No it doesn't close changeset on every change, 30 days ago I added 123 house numbers in my city with streetcomplete and all of them were in the same changeset.
It actually bundles answers to a certain quest together if I remember correctly. For example, all road surface quests within a certain time (about an hour?) are grouped into one change set. Though if you did one road surface quests and one opening hours quests they would uploaded as two separate change sets.
