Slowly working towards a viable OpenStreetMap in my area. If you want to help, you can make a free account and begin editing: https://www.openstreetmap.org/user/new
You can also contribute on mobile by using Street Complete or any number of great mobile apps that allow limited editing and full map features like Organic Maps
Edit: I didn't know about Vespucci, which is a full-featured OSM editor for Android. Thanks, @onyxjet@lemmy.world
Did the same in my area. The roads are good, but the businesses are either missing or outdated. I probably added 100 over the last few months.
It's kinds fun! When I go out, I check OM and see what's missing, take some pictures, and then go edit a bunch of stuff that night. It doesn't take long, and I feel like it's worth my time.
Thanks for providing that link. I knew about OSM, but didn't fully grasp that (duh) it's open which means I can help with the data. Time to get busy! :)
