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 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.
