@sproid Let's bring a hands on part in here:
https://f-droid.org/en/packages/de.westnordost.streetcomplete/
With #StreetComplete everyone can contribute to OpenStreetmap and help to improve the data.
If you want to do bigger changes, you can put a note there, and as soon as you are at a desktop, go to https://www.openstreetmap.org/ sign in, and use the edit button.
The tutorial makes it really simple to get started, so please try before calling it too complicated :3
