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 😁
It seems like a very helpful service. I don’t use cell data which means no GPS to contribute to it. I only use apps through wi-fi exclusively.
does it need cell-data? why? that surprises me; but then again maybe not . . .
It does not.
Nope, doesn’t need cell data
Pretty sure you can download the maps ahead of time, GPS doesn’t require data, then upload the fixes when you get home.
This is what I do, works great
