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 😁
Do you need an account?
As far as I am aware, yes.
yes, afaik
A OSM account, yes. You can join with OpenID if you want.
To contribute changes, yes. You still can share information as an anonymous user with OSM Notes, but then you need to be clear and a bit exhaustive. You can add a note that says “7-eleven” and a mapper can easily add it later, but for a restaurant called “The Coast”, for example, you need to explicitly write in the note that it is a restaurant serving seafood, details of the address and opening hours would be great too.
